Even today, Muslims on street corners in London, New York, and other Western cities are doing dawah to invite people to Islam, share their views, and convert people. The freedom of speech we are blessed with in the West allows this. Now, if you have the right to share your views, atheists, agnostics, and Ex-Muslims have that right too. Do you not see how hypocritical the phrase “It’s not a crime to leave Islam as long as you’re not proselytizing it” is? If you have the right to spread your beliefs, everyone else should have the same right too.
