Its really simple.
You speak ultra biased bullshit and have absolutely nothing to back it up, you'll be called out.
If you feel shamed - you damn should be, playing zealously one faction is shame.
Cry me a river. There's nothing wrong with playing only one faction. I stand proud to play the mighty German Wehrmacht.
Oh and almost all Korean pro SC 1 and SC 2 players are only focusing and playing one faction their entire careers. I've only seen this idiocy of playing all factions in this game. Fuck allies.
