Is this legal?

Well I didn't actually shout that loud, and it was not in a residental zone. And I was not evidently drunk. I was intoxicated, but I was not falling off my head.

And why is that word unacceptable? Is Jesus Christ and Buddha also not unacceptable?

You know fine well what you were doing when you were shouting that. Stop crying like a little ***** playing the victim card when you instigated it. He didn't even hit you anyway.

You know fine well that you were shouting that in a mocking/derogatory way.

You must be living under a rock. Let me enlighten you.In light of recent terrorist attacks, stigmatisation of Islam and innocent Muslims has unfortunately increased. Certain terrorists who carry out attacks are known to shout a phrase related to Islam - unfortunately, just shouting "Islam" or what you said for example could get anyone into trouble.The Muslim man probably thought you were referencing to that, making fun of the horrible situation instead of...whatever the hell you thought you were doing. Both of you were wrong, so I suggest you just move on and learn from your mistake. And ease off the alcohol slightly, yeah?

I came out of a nightclub around 4AM, I was very drunk(about 20 units drank).

I then shouted 'Allah hu Akbar' a few times on the street. And then a Muslim guy came up to me and got really angry. My friend told me that apparantly he was saying 'Don't say that! Don't diss my religion.'

And then he got his fist out and made a punch onto me but stopped as soon as it went to me, kind of like a fake punch.

Is this legal?

Yes, unfortunately you being an idiot is perfectly legal.

Outside a night club at 4am?
Throwing punches?
