Christians are not allowed into Mecca, because it is holiest city same with Medina. The fact that there is muslims in Axum means it isnt as holy as you want us to believe.
Besides Saudi Arabias constitution doesnt pretend to be fair. In Saudi constitution Islam is the only religion they accept unlike in Ethiopia where there is freedom of religion. Your arguments are void and null, they make zero sense. Just admit it that what is happening in Axum is infact oppression.
The fact that there are Muslims in Axum freely praying even renting homes from Christians shows they have the rights and there is tolerance. No one is stopping from existing. Oppression implies they are being prevented from being Muslims in Axum when that is not the case.
