The USSR tried to forcefully abolish religion. It was a terrible move. That doesn't mean that people will form reactionary cults for all time. Religion as you know it emerges from material conditions. When we change material conditions, religion as we know it will cease being maintained by material conditions. Religious reaction emerges from this as reactionaries attempt to change material conditions to maintain the religion as it was. All we need to do is prevent that regression and the reactionary aspect of religion will whither over several generations.
Reactionary thought is not innate. That's ridiculous. There is no such thing as contentless reactionary thought, that's idealism. Reaction is context-specific and it does exist in the absence of specific changes.
You are making an argument from human nature, something you, as a communist, should know is completely unfounded.
I cannot believe you are comparing being a reactionary to being queer.
