Dude, please read the whole of my post.
I, and everyone else here, don't want anyone to feel like they can't post just because their grammar is a bit poor... good lord, I'm hardly a shining beacon myself.
But that wasn't my point anyway, it was about voicing and defending an opinion about a thing/idea versus giving an opinion on a member of the forums.
There is a difference... the former is fine, the latter isn't as 99% of the time, you're going to insult them.
Here's another example... years ago, like, 7 or 8 years ago, I wished all the girls on the forum a Happy Valentines... not knowing that Sara was an abbreviation for Saracen
He took it in good humour but he could've equally gotten snotty with me on it... so even when you're trying to be nice it can go very wrong.
