I have plenty of internet "debates." Here is a list of categories I wind up "debating" usually. I consider the people who are on the other side of the "debates" stupid, silly, and/or crazy, at least when it comes to any of the issues I'm pointing out below. Yes, many people show up on a few of the categories.
1. Young Earth Creationists
2. Evolution Deniers
3. Holocaust Deniers
4. Those who use the bible as evidence for God
5. Those who call atheism a religion, or liberalism a religion
6. Those who believe the side of the terrorist is the side of the victim
7. Those who think that we shouldn't piss off Islam because we will get what we deserve if we do
8. People who think that homosexuality is a choice in most cases, if not all cases
9. Those who think the Protocols of the Elders of Zion is a real document
10. People who say there is definite proof that Jesus and/or Moses existed
11. Those who criticize Israel, say they aren't anti-semites, but fail to criticize other world wide conflicts or regimes
12. Anyone who thinks the UN has any use today other than help Islam spread
13. Those who have a problem with Israel's legitimacy, but doesn't have an equal problem with the legitimacy of Canada, the USA, and Australia, etc.
14. Muslims who whine about less than 500,000 Jews going to the non sovereign region of Palestine from Europe, yet have no problem populating the West by the millions
15. Those who say that Israel is guilty of genocide
16. Those against gay marriage
17. Those against the woman's right to choose
18. People who own pitbulls (ok, that is not an internet one)
19. Those who know for sure that man has absolutely nothing to do with Global Warming
20. Those who think that God creates miracles or disasters
I could probably go on. But it is my birthday in 2 and a half hours.
