It might do, you can't really predict what people will be offended by. Then again offending people in and of itself isn't illegal.

It's been used in horror films and by gothic and metal bands for a while, supposedly because it's 'satanic' (because by inverting the regular, or Latin cross, they are 'mocking' it), but St. Peter - the OG Pope - was crucified on an inverted cross, so it's sometimes known as 'the cross of St Peter'

I've been to a few local stores featuring Halloween decorations and not one of them had an upside-down cross. You have seen too many movies, troll.

I think some people would be triggered. It kind of irritates me tbh.

I don't see the offense. anyone who is wearing a cross sees an upside down cross everytime they look down at it

No it won't offend anyone. It is also not illegal.
