I don't feel the same way. I avoid a few topics that people probably would call me an extremist for opinions about, but they're rarely topics of conversation anyway. The internet is full of people from all ends of all spectra, so inevitably everyone will be called either a literal Hitler or a literal Stalin given enough time on the web. That doesn't make either of those extremes correct, nor even worth considering. They're both absurd, as you say, but that doesn't reflect poorly on you, but rather on the people making the claim.
