No compulsion means no restriction on anyone’s beliefs. One can belong to any school of thought having equal basic human rights. But having an opinion opposing to a specific school of thought and then asking to be called a part of them is totally different, it’s like making and accepting Newton’s fourth law of motion. It doesn’t mean you can go around allowing non-muslims (Ahmedis in this case, who do not believe in the finality of the prophet (saw)) with their non-Islamic practices declare that they are Muslims and they represent real Islam.
Do you know, Ahmadis make false visas and hide their identities while going to Ka’aba Tullah are usually cause of menaces such as harassment and begging in the name of Islam. Today, those who are found on Twitter exploiting the religion are to no short of liberal hypocrisy and exaggeration from their inward bias.
