Do you have a cure for the idiots who say "My way is the only way"?

Sure thing, and it is made by Smith&Wesson Laboratories.

Yep. I remind them that "their" way is only a modernized version of "my" way.

"How do I attain Gong Fu?" asked the student of the sifu.

"By following The Way."

"But what IS The Way?" asked the student.

"The Way is YOUR Way, which is different from MY Way."

I just smile and nod and let them know that I'm understanding of the fact they are narrow minded.

That normally shuts them up.

I say that Islam is the right way. Notice I said the "right" way, not "only" way. If you want to worship something else, feel free to. I'm not going to pressure you into Islam if you don't want to.

As-salaamu alaykum - Peace be upon you

Well, you could always lynch them but the best cure is not listening to them.

Ignoring them is least stressful solution

I'd say "Sure, very nice", then I walk away ;)
