None of my daughters hang out with older boys/men ever so it'd never happen BUT...
My brother is into all that shit and has been for longer than these guys, likely. I grew up with all the Japanimation - you name it he has it - but never cared for it myself, and (at least at a root level in a few nuggets) for the same reason as you. I just don't understand it or dig it.
Here's the difference tho. I really don't care what they meme with so long as it's relevant and preferably funny.
Dogs, cats, ponies - take a look at this site. The same shit is posted, reposted, and I saw a meme tonight that was making fun of reposting! I can guarantee on a drin page meme there will be no less than 3 repeats of the meme itself or other garbage just for upvotes. It's lazy.
I like to think I've earned my points because what I do brings a laugh to someone. Whether they are the pink pony guy or an actual computer-using dog, doesn't matter. On here we battle wits, not gender, sexual preferences, or color of skin - because it doesn't matter and never will. We are memers, we make fun of and exploit what we can in the name of humor.
So I guess what I'm saying is, I appreciate the warnings as discussions about it all so I know more. The golden rule for me is:
We can get along just fine if nobody acts like a c**t.
