I wouldn't say 'always', and I don't recall ever mentioning the word 'suck', but it does occur that I target CDF when they lose a game. That is mostly because I see people praise CDF, saying it is a powerful, succesful clan etc. Then I really like to point out to them just how 'mortal' they are .
And what is wrong with saying "CDF gets it again", or "congrats on not being asskicked by T3 again". That's just observation. I don't hate CDF for the sake of hating it. I'm expressing an opinion, one you either like or despise.
But if you want me to shut up about CDF, I will gladly do so. The last thing I want is to have this situation escalate any further. But when I see someone praise CDF again, I will load the cannons and fire at will.
