like banning lgbtq people from kissing outside cause it makes others uncomfortable.

We're talking about bans in workplaces here. And I think that your example is fitting. If a workplace can ban people kissing (or wearing a pyjama then it should be allowed to ban religion affiliated clothing as well. That sad, I do be live that in most cases employers shouldn't be allowed to ban these things. If you end up working with your boyfriend and occasionally share a short kiss, that's not going to affect your work and if you're able to do your job in your PJs, then you should be allowed to do so.
