A common Muslim like yourself might say these actions are barbaric and not representative of your religion. But Islam isn’t having a reputation of being wholly arbitrary. A vast majority of Islamic scholars will and have justified the injunctions against Rushdie or any blasphemer.
And fundamentalism is a misnomer when it comes to Islam because any deviation from fundamentals is violently opposed. It’s a religion that never moved away from fundamentals. It has never had any reform that secularised and drew power away from the clergy.
You are probably a good, kind person but when this happens to Rushdie or any blasphemer it represents exactly what unreformed Islam is.
