I have this theory that pre-dates the internet.

Most racist bigot homophobic xenophobic anti-semitic types learned it at the dinner table from their Archie Bunker dads. Who learned it at the dinner table from THEIR Archie Bunker dads.

Now less than 100% do because the internet does poison some of the weak minded out there. But between the racist bigot homophobic xenophobic anti-semitic chatter on the web and the current gaggle of Archie Bunker racist bigot homophobic xenophobic anti-semitic gun-nut dads...there are still plenty of violent racist bigot homophobic xenophobic anti-semitic gun-nut extremists out there. More of them than ever it seems and younger than per usual.
