Well, that's a good point. You're right about the use of Biker Gang as a pejorative being in the same vein as your statement. I still think that I agree with the point that he's making that in a community which is inclusive enough you'll find people there who are openly hostile, and that you have to choose whether you accept the hostile people or the people they're hostile to. Depending on your choice you might then end up on the wrong side of history, irrespective of your original goals.
