Well, the suits thing was mostly a joke / provocation, I don't think anybody who shared that post really wanted to ban suits instead of stopping to ban hijabs.

Saying that "all religious symbols are banned in the same way" however is misleading: in an area where the religious people are mostly part of either a dominant religion that does not mandate wearing any visible symbol (and if they do want to wear one, it's usually something small and easy to hide like a cross pendant) and one that is discriminated against that mandates that its followers must always show visibly their religion, such a law will not impact the followers of the former, but only the followers of the latter.

Also, there are laws that are not against religious symbols in general, but just against specific kinds of dress (especially the burkini, afaik) under the excuse that they are a symbol of the oppression of women and those are even worse: if a woman is being forced to wear a burkini when going to the pool, and the pool forbids that woman from entering while wearing a burkini, it's not like magically she can wear a swimsuit, they have just forbidden her from going to the pool.

So, yes, these things do have an impact, one that adds more burdens and discrimination to the weakest parts of society.

(disclaimer: I'm talking about the laws and proposed laws in Europe, mostly Italy and to a lesser extend France, I don't know what the situation is elsewhere well enough to have an idea )

(disclaimer2: I know that not everybody who is religious in Europe is either christian or muslim, but at the moment the political debate is on those, everybody else I'm afraid is going to end up as collateral damage)
