Good Friday means absolutely nothing to me. And I'm not sure why you feel every single human being on the planet should have to stop what they're doing that day so it can be sacred for you.
This comes under traditions linked to the culture that happens to have the religion, as opposed to the religion itself, which is a distinction few bother to make.
The traditions are just that, if some find it sacred then that's the part that's linked to them finding a certain religion's teachings to be true. That's where discussion should be had but which is taboo to have. Either they are correct and we are all disobeying their god or they are wrong and are obeying an imaginary entity, which is only considered a problem once someone thinks that god or the supreme entities want them to harm others and/or themselves.
What we have is people like yourself saying that what is sacred to some can just be left alone by others and I agree, I will leave alone the halloween and good friday but actually there comes to be a problem when a nation that has a lot of expats, like UAE, blackmails everyone in the nation to (at least in public) adhere to Ramadan fasting. Even for the Muslims, there are problems. It is known to have caused severe accidents on the road due to already-malnourished taxi drivers living on barely any wages having to not drink even water from sunrise to sunset (and that's extremely long there). When circumcision is forcefully done to a baby/toddler we say it's okay because we are being rude bigots to say no, except that there are sects based on African Islam (Sudanese in particular but others too) that practise(d) female circumcision and there were Muslim residing in nations it was outlawed abusively taking their 14 year old daughter or whatever to undergo female genital mutilation and played the 'bigot' or 'prejudiced' card when and if any investigation took place from the nation they flew back to reside in after having mutilated their daughter off-shore. Obviously it's worse on the females for physical reasons but where and when can we challenge anything? What is or isn't the real Islam? Who decides and how do we challenge that without attacking an ethnicity and instead only their religious ideology?
There is also a severe amount of subtle blackmail (or overt) involved with many religions but undeniably Islam. If you leave Islam, especially as a female, you are treated so badly you probably won't believe it unless you've directly come across it in documentaries or from people you know. I am talking about a family arranging to murder their own daughter, niece etc simply because she wants to pursue further education and didn't want to marry some older, probably abusive, guy when she was barely legal (often underage). They call this 'honor killings' and we are told we're bigots and assholes if we question if such a religion and ethos with all the things aforementioned and more to worry about, should be truly introduced to Western cultures.
What they tend to do is say 'Christians have been just as bad' which is why as someone who sees the flaws of both Christianity and Islam, I don't quite understand that argument. It's so taboo to even dare challenge people on the darker side of their religion and its practises, let alone concrete teachings.
I could type more, a lot more, however I'll leave it at that because honestly I am fed up of the left-wing pandering to such far-right ideologies and don't want to be seen as some far-right bigot myself because of cancel culture.
To be clear, I'm not only having an issue with Islam, I just find it full of many overt, severe issues. I am saying if your religion is correct, if your god is the real god and if your moral code is what you believe is right, why is it I can't get a concrete answer on certain things? I am not saying I judge one adherent based on what another does, I'm saying I'd like discussions to take place on what is and is not that religion without it being taboo to dare say a word about.
