No. But then not teaching about sexuality isn’t fundamental to Christianity, we have plenty of gay vicars for instance. Not having images of Allah is fundamental to Islam though. Again, if you’re going to compare eggs try comparing them to eggs.
Just to add. I absolutely support their right to protest it though, even though I disagree with them.
How long did all branches of Christianity preach against homosexuality? It was within my lifetime. Remember Section 28? First female vicars too. This is still a massive thing for Catholics. DUP are massively anti-abortion and homosexuality and want it banned and they're Protestant.
It changed because people basically abandoned the church because of views like this and they were forced to change to have even the slightest semblance of relevance in the modern age. The church would've much rather maintained a ban on homosexuality and women priests if they could and if they'd have maintained enough hardcore support to do so would've.
That's how Islam gets away with it - lots of followers refuse or are to afraid too slightly question stuff like this so they can get away with the hardcore. If they could get enough to show dissatisfaction with these archaic doctrines they'd have to make the same choice - get rid of it or become irrelevant.
Things like this It's far more lack of understanding and tolerance for this society than a lack of tolerance of society towards Islam
