Acknowledging the existence of obvious branding or political affiliation means subjecting yourself to an inquisition where 30 people take turns trying to pigeonhole you as a bigot.

again the message is clear "you're not welcome"

As it happens, though, I don't see myself as a victim. I don't mind in the least people reacting to my opinions. But I also feel perfectly comfortable pointing out the nature of the reaction, which is generally not to engage with content but to turn it into a question of character. Which you have done.
