Yes, they do, but one side (the ALIPAC side) seems to label those who are for Bush's policy on immigration "for illegal immigration". Now, I don't really care for his immigration policy myself, but I hardly believe that those who do are FOR "illegal immigration". To say so, is a classic strawman argument.
What these people are doing, imo, is rather petty. It probably stems from purely personal dislikes, and ultimately has nothing to do with the topic of immigration. What I think everyone should do, is take a few hours (if not a few days) off the computer as a whole, and compose oneself into the adult we're all supposed to be.
And again, this is clearly not a "purging". I'd like to see anyone try to justify calling the banning of 9 posters out of the thousands that post here every day a "purging". I'd laugh in their face.
Race baiting is as flagrant a violation (or so should be considered) of posting rules as any other.
But alas it ain't my forum.
