Bible

Old Testament is Jew territory. Jews generally aren't anti-gay. Maybe they understand their book better?

There actually was a real person named Jesus. But different people believe different things about what he did. He's as real as any other famous historic person. I believe that Muslims don't think he's the son of god but Christians do. There are records of Jesus like any other person too. I don't think scientists can argue he was a fake person because there are facts proving he is real.

Pigs : Never says pigs are an abomination, in Leviticus God tells the Jews not to eat pork(or any hooved animal for that matter) because it is an "unclean" animal. Old Testament, is no longer in place.
Defacating : I have never read where defecating is an abomination and I'm a ministry major, I would love to see a verse for this one.
Period : It speaks about "associating" with a woman during her period, some people believe the way it is speaking it means "to have sex" others think any form of interaction, but periods themselves are completely natural an abomination
Clothing from two fabrics : What the pagans wore, and was against Jewish law because they were to be seperated.
Two seeds in the same field : Again, not an abomination, just a decree, I do not know why this one was banned in Jewish law though, Leviticus 19:19 talks about it
Picking up sticks on the Sabbath : Any work was against the Jewish law on the Sabbath because it was set apart, Jesus cleared this decree up though when he speaks about how it was taken to the extreme by the pharisees and is more of a guide then a law, meaning you should try to avoid physical labor, but there is exceptions.
