If you're unable to engage people in a reasonable way, then you're just as much of a problem as I am regarding progressing equality. People who mostly agree with you don't deserve a novel belittling them via straw man.
Im not one for centerism and half measures, and I fully get the idea of the paradox of tolerance; but you're exhibiting conservative purity culture, which is the very real failure to deconstruct our upbringing that causes progressive movements to constantly self destruct.
