I don't have anything to say but wanted to use an alias just to see if you'd get mad at me for it.

Fucking pussy!  Who the fuck do you think you are?  Fuck, fuck, fuckety, fuck!  I get all my aliases at Aliases-R-Us.  Fucking fucker.  I mean, fuck!  And no, I'm not really MP67, I just play him on TV.
LMAO!

your right to use an alias.  But if I ever find out who you are, I will come to your house and kick your butt for doing so!

Fucking Alias!!!

Some guy cut me off in traffic, leaned out the window and said "fuck you-you fucking alias".

Zzzlong as you're not flaming any one, or using it merely to stir up trouble.
Controversy can be edifying and cathartic; but "trouble" for trouble's sake is bad.
Aliases are a great tool for alowing an innocent and benign anonymity when subject matter could embarrass/libel the author or innocent associates.

Flame and cause trouble via alias? You will be found, and you WILL be judged.
