I used to be like that, not even very long ago, but it has changed. My love for God and the desire to do His will changed me, I love (don't misunderstand this word) all of humanity, I want everyone to know God, love Him, be the best version of themselves and love all other people and treat them as they would themselves. But that's very far from reality and would seem absolutely impossible and just a dream. But I believe in this dream, I think it is possible and can be made into reality, so I decided to dedicate my life to doing whatever I can to bring it closer and trying to change the world. How exactly I'm going to do that, I don't know, but I give my life to God and want Him to guide me and use me to realize His will through me. I've thought a lot about it and I could find no other true purpose in life.
This has been my biggest motivation and guidance for the past ~3 years. But I've had various different ideas about making this dream a reality. Well the first thing that got me on this path was realizing the horrible state of the world today, mainly through various videos and websites online. Eventually I found /pol/ and would spend a lot of time on it. I learned a lot there (a lot of which was also not true) and I learned it all in a short amount of time, so it was a big shock to me and caused a strong emotional reaction.
I cared about politics and the fate of my country before /pol/, but at that time I was young and faith wasn't as important to me as it is now. After /pol/ I cared about my country and my people even more and also started caring about all of Europe and "the white race". I believed we were better in every way and should kick all muslims and niggers out of our contries (with violent force if need be) because they were making our civilization worse and we should remove all jews from power (again with violent force if need be) and lock them all up on some island away from any other civilization. I never got to the point where I thought these people should be mass murdered, but I believed that they should be separated from our civilization and those that resisted could be killed. I guess you can call that hate.
It took me a while to grow out of my hatred and racism and I would say that my love for God and wanting to know His will was what helped it the most. And I got those things because after deep contemplation of life I found true meaning only in God.
Also don't misinterpret what I mean by hatred and racism. To me it's certain that there are big differences between the races and all of them have their strengths and weaknesses. There are also even greater differences between cultures/civilizations, and mostly unlike in races, some are vastly superior to others. The European/white culture/civilization is objectively the best and superior to the asian, muslim, african and all other cultures. Culture is much more important, and if someone is christian, virtuous, adheres to european values (true european values, not the modern cucked understanding of "european" values) and wants to change the world for the better then I don't care in the least what race and nationality he/she comes from. We are all united through God because we all descend from Him, and so we should, because of our love for Him and our brothers, strive to work towards the common good (true good) of all mankind.
The only people who I consider enemies are those who know and understand God but reject Him and choose to work AGAINST His will. If they can't be made to truly give up their evil and come to God then they are the enemies of God and any power they hold must be taken from them and they must be imprisoned and isolated from society or if that's impossible, anything must be done to remove their poisonous influence. Such people are rare, but they do exist and a lot of them are very powerful. Others are mostly just misled and deceived to certain degrees of severity and/or ignorant or stupid, so we should try to help them first.
But as I already said, the world today is in a very bad situation, and because of that we need to set our priorities right so that this situation can be resolved positively. What I mean by that is that we need to preserve the european/white culture/civilization, but not at any cost. We must defend it from both outside forces and inside forces, and prioritize it's good above the good of others (because in the end it will end up being the best outcome for everyone). The "outsiders" that want to destroy it must be stopped, but if we abandon our values and christian principles to stop them, then we will destroy the very thing we wanted to protect. The "dehumanize yourself and face to bloodshed"/save ourselves at any cost mindset is destructive and goes against it's own goal.
tl;dr/short answer: Learn more about God with honest intentions, understand Him and then love Him and seek to do His will. It will improve you in all ways and guide you to the truth.
