I'm not gonna give a giant dissertation, but just say this
Just saying "Xenos west" while fighting is fine.
Wanting to play "OH GOD SARGE THE XENOS GOT ME OH GOD OH FUCK" is fine
Running around in game spamming "Nigga Gucamole Penis Based BALANCED AND FAIR" and other dumb shit is what get people in trouble. If I wanna read that all day, ill go play CS:GO
