Don’t put words in my mouth. Voting differently than me isn’t a deal-breaker.
The beliefs I mentioned, which public figures like Cernovich endorse and use to earn their bread and butter? THOSE are deal-breakers. You’ll find rape apologists and spouters of certain reprehensible Far Right talking points all over the political spectrum. If I won’t silently accept that from other Lefties, why would I do so for bona fide Right-wingers?
BTW, if you want to avoid looking like a condescending ass yourself, avoid phrases like “echo chamber.”
