Some people are terrified of anything Arabic sounding, especially people speaking Arabic. It is not racism to say that. It would be racism to say that all white or black or whatever people are terrified of anything Arabic sounding.
But there is nothing even remotely racist about saying some people are scared of something that has to do with an ethnic group.

Exactly! Isn't that what he implied? He didn't say "Here are some pranking options that would work on some people" he made a general assertion "Here are some pranking options" meaning they would work on all people meaning all people are terrified of anything Arabic sounding.
If I throw a banana peel on the ground like the prankster I am, my expectation isn't that everyone is going to slip on it. Most people won't, but I might prank someone if I'm lucky.
