( Hey Bud,would you not mind wearing your kilt? I have some buddys coming and two are very homophobic )

...and they need you to do their thinking for them?

At one time or another I've made judgements about people based on how they look and how they're dressed. I'd say that 90% of the time I've been wrong; they almost all think the kilt is cool...and some of them even have kilts themselves. Your "former friend" did all of his friends a big disservice.
