I replied to your troll meme because a) if wasn't funny, and b) it was referring to me (at least in part). Conversely, I upvoted your anchorman gif, because it was actually funny.
I see Yasuo about as much as anyone else sees him, and I wouldn't say they are all bad (for instance, the Yasuo in my game the other night was mastery 6. I made him ragequit before 11 minutes with Xerath). Neither are my main champions his counters, seeing as my main champions are skillshot based or ADCs (I.E., skill matchups at best, to champions Yasuo actively counters at worst).
I have been beaten by numerous Yasuo's, plenty also that are just straight up better then me and I promptly got my ass handed to me.
If your argument depends on the assumption that the only reason nearly all of your Yasuo comments are donvoted to usually -2 or lower is that people are playing URF (a varient which isn't at the height of popularity right now mind you), you are scrambling for validation and looking for a scapegoat.
And to answer your question as to way a good number of nerf threads are downvoted is because very often, they are nothing but complaints with no actual substance, usually by people that just don't like that they need to change their playstyle to beat a champion.
