Oh, I look in now and again.
Now, you would have to have quite thick skin to be posting contary to the jihad gang on LF, and would be an endless firefight. Plus, as I said, from the conversations on the site it's obvious that people disagreeing with that particular set aren't meant to be invited in. So the site does tend to suppress views that aren't pro-palestinian, for example.
Then you have the fact that the "cadre", the folks forming the initial backbone of the site, are types who would be at home on VanguardNews - the "vanguard language manual" with its rich set of anti-Jewish epithets like "kikes" and "hymie" isn't yet fully implemented but posters like Madrussian are getting there.
The problem with all that stuff is of course that the general tone of the site will attract more of that kind, and it will keep others away. Normal people usually don't want to invade a lair of frothing jihadists to argue with them. The converse is true, however - frothing jihadists will invade a normal site at first opportunity.
Fortunately, I have skin like a rhinoceros and 'dead meat is my specialty'.
Possibly. Personally, I think the refer-a-buddy system is what does that. The bigger danger, IMO, is that an open group will attract more of that kind and the opposite kind, and devolve into a huge flame war. Which might not be so bad if it were an on-topic flame war. That's what the ratings system is supposed to circumvent, but we'll have to see.
