Well, considering most of my life revolves around proving myself right, with logic mind you, I may seek out fights, but by God I make sure my side's correct first, I have quite a few pet peeves as far as fail come backs go.
Firstly: Evolution is just a theory/ Why are there still apes around if evolution is true.
I hate this comeback more than anything else, I had this argument with a religious nut at my high school, and he pulled that one out, to which I didn't respond. Now though, I have a great comeback for it, which everyone should use in someone does pull it out 'We have the same ancestors, not the same parents' which might confuse them, but to really piss them off 'Apes are considered our 'cousins' not brothers or sisters, we went along a different evolutionary path than they did'. It will either A.) Enrage them, which is always funny. Or B.) Make them struggle to come up with something better, which will take a few mins, meaning you win.
Secondly: Show me proof that God exists/ There is no proof that there is a God.
This off-sets my first argument, but basicly I was arguing with my cousin who was an Atheist just because it was cool for him to be, not because he actually WAS one. We were arguing, and he came up with that gem, to which I curtly responded 'There doesn't need to be evidence, as long as someone believes in him, he exists'. I tried to use the concept 'I think, therefore I am' but apparently I did not word it clearly enough for people here. So! Basicly the concept is that no one can disprove God exists, it's one of those things that's impossible to disprove.
and Thirdly: I'm not for [insert argument case here] because it's not Christian.
I prefer this one more than the other ones, mostly because it, at least, doesn't mean that you are wrong in an argument. I heard this when talking about 'hot topic' subjects with her, and basicly she did not support those things because it was against her religion. I can respect that honestly, but when the day ends, it's all about what YOU do, and YOUR actions, not about what God does, or what your faith does. Everyone is an individual, and capable of making their own arguments, and cases, so a religion, or government shouldn't decide what is right, or wrong, for you.
