Honestly, not just with memes. With comedy in general too. After years of witnessing stuff, I've concluded that some people (NOT ALL, JUST SOME WHO ARE RABID ABOUT CERTAIN STUFF) forgot that there's more to life than finding things funny. Admittedly, I admit that there's stuff I don't find funny even with comedy but I can also admit that there's more to it than that.
I mean, I never found the whole "beating the dead horse" memes funny but I don't recall bringing 'em up all the time. That's one example I can think of.
Black bear or not, be sure to remember that scenario. And hopefully you'd realize why some things were happening to begin with and maybe I'd be less tolerable.
