They are not for obvious reasons. Just look at Hutardo's own words regarding this in OP's second image. Baptists who use the staurogram, use it without any knowledge of its role of visually portraying Christ in the early copies of the New Testament texts. That's where it came from.
Because of it's role and how it is used in its earliest days, what that proves is that its function is that of a simplified form of a crucifix anyone can see in a Roman, Orthodox or Lutheran church. It isn't the same as a Baptist like you claiming to support how the early Christians use it
