Why do so many alleged feminists and leftist support this religion?

You respect people’s right to choose their religion. Then you still judge them for their beliefs and actions.

You can be Muslim and eat pork and think women are equal. You can be Christian and not go to confession. You can be Buddhist and believe in violent response to violence.

The made-up rules of each religion are made up and enforced by the people that are in that religion. Those can change.

And I choose to believe that we cannot accept such ideology in a western society as it is fundamentally counter to our founding principles. Its a paradox to force me to accept freedom of religion on the bases everyone gets to choose their beliefs. You saying I don’t have the freedom to choose not to believe in other peoples freedom of religion?

it is fundamentally counter to our founding principles

One of our founding principles is freedom of religion.
