There is literally not one filioquist Catholic who thinks that the Spirit is any lesser than the Father or the Son. If claiming that the Spirit proceeds from the Father and the Son somehow implies that the Spirit is lesser than the Father and the Son, then you might as well say that the Son being begotten of the Father makes the Son lesser than the Father, which is nonsense. Just as the Son is begotten not made, the Spirit proceeds and is not made, and all three divine persons are equal and distinct as persons.

Pope Honorius I was posthumously anathematized for the heresy of Monothelitism at the Third Council of Constantinople. The decision to declare a Pope as a heretic must, of course, come from the magisterium as a whole rather than from laypeople on the internet, but it did indeed happen once.
