Shunning doesn’t stop it. Over indulgence is not the only harmful part. No alcoholic started off drinking a bottle of whiskey a day. You would NEVER say heroin is not risky and harmful if you only shoot up once yet both have the same potential.

Mastering temptation is refraining from the act, not dabbling with something dangerous.

“What does your religion say to just do it to those that are not like you like the kafir“
You’re genuinely misinformed about Islam and getting it mixed up with Judaism. No where in the Quran does it even suggest unjustly treating non believers, provide me with evidence if what you say is true.
