Why only religious beliefs protected?

[FrustratedFool]

But it's not an intrinsic or fundamental characteristic, nor religious?  

So why give special protections to single people because they are single?

At present, it seems like you're just finding ad hoc reasons to justify the status quo.

What about gender transition (same law)?

Gender transition should be protected. Primary reason being that it encourages the acceptance of transhuman values.

It seems you think it reasonable to offer legal protection to a recent convert to hari krishna because religion has been around a long time; protection to a single person because marriage is very valid; protection to a white person because race is fundamental; protection to a transperson because it encourages transhumanism; but don't think a sincere and life long Marxist Vegan should have any protection because those beliefs are dangerous.

To me that seems unreasonable, unfair, and bad for society.

Oh well.
