Facts confuse you, don't they? It's not your fault, indoctrination to be against views contradictory to your own, no matter their validity is hard to overcome.
Here's a quick fact. Before Islam took over with blood, Zoroastrianism was the dominate religion. Under the Avesta, slavery of any kind was forbidden. In fact it was very rare, and almost non-existent. Because all you had to do was publicly declare yourself a follower of Zoroaster, and you immediately were set free.
It's ok, I understand. You're just like all those who espouse white racism as legit so not really racism racism, who don't understand there's a difference between the people, Muslims, and Islam, the religion. You can't be an anti-racist, unless you're inclusive to all races. For many that's a hard concept to grasp.
Muslims for the most part are a good people, Islam on the other hand is a terribly homophobic and exclusive religion, if followed completely.
Any religion can be bad or good, unless you become a fundamentalist. Except Jainist fundamentalist, who'll just smother you with compassion and tolerance. If I were to have to pick a religion for the world, that's the one I'd choose.
Got it? Thanks. Have a nice morning.
