This is the kind of thing that kept me out of the fandom for years. I have zero interest in hearing how bad you think Discovery or Enterprise or whatever is, but by God you and everyone else will be sure to explain it to everyone repeatedly.
Only when asked. It's a legitimate point for discussion and it comes up from time to time and so what? Can't you read the subject line or look at the meme (see: OP) and just avoid clicking on the discussion? Why are you even here to read this? You knew what it was going to be!
The only thing that's wrong around all of this is that when I give my perfectly reasonable and widely-held opinion, I'm liable to be fucking banned for it in certain places because people like you are wielding the hammer.
This keeps you out of the fandom? Jesus H. Christmas, maybe you need to spend your days in a room lit only by candlelight wearing earplugs and doing nothing but reading actual paper books? This is every fandom in existence on the Internet without exception.
