I know this was meant in a positive light, but didn't you just "brag about dumbing this game down" by stating the fact that you didn't know what you were doing in your past tournament achievements and belittling all of your opponents? How relevant even is that to your message?
Now, I don't speak for GULLY (although our ancestors are straight out of Africa, so perhaps there's that African connection) but do you really think GULLY trash talked because he was proud of himself for winning? People trash talk because sometimes it's fun and/or different to act out on an online community. As you mentioned, this game objectively sucks (and I agree!), so people like to spice it up w/ some antics. I'm not necessarily a fan of trash talk (a ton of people love to spectate trash talk/drama, btw), but I can recognize why it happens. Perhaps shit talk was nonexistent back in the "good old days", but I personally haven't heard of any online competitive gaming communities that force all of its members to act prim and proper all the time.
At the end of the day, people go on this site to have fun. Do people find WhiteQueen annoying? Of course. But if, as you said, your goal should be to "try to get some fun out of something that was never meant to be played competitively", I'm sure WhiteQueen is having more fun being WhiteQueen than just being some square dude. On top of that, there's a fair amount of people (often, myself included) that find him entertaining. Again, it's an online community that people go on as a hobby, you'd think you should be able to be selfish and have fun your own way when doing something for your own entertainment on your own free time.
