Ill throw in my two cents. Of the 46,289 members currently registered on this site, 99.8% of us can conduct ourselves in a calm and rational manner
One of the first rules of online communities is, "beware of participation inequality." Those that contribute most tend to be those that are the most passionate, and those that are most passionate tend to be the most biased. The rule of thumb is that in any web group, 90% are lurkers, 9% do something now and then, and 1% contribute the vast majority.
Of the numerous consequences, the 2 basic ones are 1) you never really know what the majority is thinking, and 2) the stuff you're reading is usually very polarized.
So even though the guys ruining it for the rest of us are very few, their contributions add up to a (perceived) disproportionate amount on TFL, both by frequency and extreme awfulness.
For me, I think the bigger issue, more than racism, is the "I-was-here-first,-so-get-yer-stinkin-____-outta-my-backyard" mentality. Well, having citizenship status does technically entitle you to such comments, but I think it's the wrong approach. I don't think anyone here actually is comfortable with letting people just hop the border - just on how to confront them should they try, or if they're already here. Personally, I don't think the average illegal immigrant is looking to rob trains or steal our women; they just want to make a living - it's the 'starving man who stole bread' situation.
As for racism, I don't think the issue is as taboo as so many try to make it out to be. Funny how the people least comfortable to talk about race issues are those who have been accused of it. Like how some men get really riled up when when their sexuality is questioned.
We are humans, and we harbor prejudices - it's natural. It can be something as seemingly harmless as having a preference for blondes, or joking about how white people can't dance, to real, outright hatred. I actually believe that the former is more dangerous, because it's the kind that nobody is willing to admit or talk about, not even to themselves. We cannot play one giant denial game, pretending that we're all objective, unbiased, and indiscrimate. We're only human. At least the latter come bearing torches and bedsheets over their heads, so we can pick them out.
"I'm not racist. How dare you accuse me of being racist. Stop playing the race card!
Some of my best friends are not of my race, so there!"
I see no problem in talking about race issues, if conducted with civility. Too many members are too quick to accuse racism, while others play the "race card" card (not a typo). It's better to confront the issues than to pretend they don't exist. Remember when that book, "the bell curve" came out? Everyone was so quick to play the race card or the anti-race card, that nobody really stop to consider the consider the consequences or underlying causes for the findings.
But I see no place on TFL for illegal immigration. It has no track record of maintaining civility. In fact, after one poster implied that he was itchin to go shoot aliens, I quit reading any thread about the subject.
I'm just guessing here, but I bet that at the current moment, there are more active threads about aliens than... gun holsters. On a gun forum. this alien topic (nice pun, huh?) is only going to get bigger and bigger I feel... until the L&P forum has to renamed to "illegal immigration&L&P"
