from a religious standpoint your friend's view is rather logical. from a political view it makes enough sense too. i think you are possibly a little to ignorant and just being judgmental. you should probably talk to your friend about it because his point of view could be quite reasonable.
But I don't believe gay marriage is wrong/evil. As for abortion/conticeptives...I believe a woman should have the right to use birth control. Abortions though shouldn't be thought of as a "get out of jail free card." I believe if a woman is raped, she should have the right to be able to choose to use a morning after pill, to get an abortion or to keep the baby.
As for drugs, I believe you can become addicted to/abuse almost anything. Not just alcohol or pot but also food, people, electronics...Like you mentioned before people, humans have been intoxicating themselves for thousands of years... It is of my opinion that it is good to know when to stop. To be educated on what it is you're putting into your body...
I guess what I take issue with the most is how my former facebook friend seems to suddenly view the world in such harsh black and white tones. That they seem to believe that if somebody is romantically involved with someone of the same gender that it's evil, THEY are evil...
