I'm generally happy to write walls of text to debate ideas, but I'm not very inclined to do it for people who just drop links. I will however drop a link of my own:

TL; DR: Everyone hates their outgroup, and everybody has one, including you and me. Isn't it rather convenient to convince yourself that everyone in your outgroup is intolerant totalitarians, so that you can continue to hate them and justify any kind of tactics against them while also patting yourself on the back at how tolerant you are? (The 'you' there doesn't mean anyone in particular, just a general statement).
Tolerance means not hating your enemies, your outgroup, and is genuinely hard and pretty rare. Everybody likes their friends and allies, and there's nothing particularly special or virtuous about it.
