Well, not exactly. Like, imagine your best friend is pro-conservative; he's a really nice, polite, sensitive person who's mostly willing to hear opposite viewpoints.

Then you watch his posts on r/the_donald, and he's acting like a sneering, disgusting douchebag, ranting about "libtards" and how lefties are morons bent on destroying the fabric of the country?

Sneerclub is the same. I can totally believe that most people there are reasonable people with reasonable concerns, but the community brings out the worst parts of them the same ways others like the_donald and TheRedPill do.
