Lisping, giggling like girls, zipping my jacket up and down when I disagreed with a priest (that bugged my wife!), sexual innuendo relating to strong masculinity (coming from someone being effeminate), excessive hugging and patting, "nuh uh you DIDNT!" [female ways of speaking], etc.
That kind of thing is off putting.
I've known only a handful of priests who fit this description; however, I can think of at least one that fits this description who is also one of the better priests I know and who is quite well loved by the students at Holy Cross (I'm sure any students or graduates of said institution have a pretty good idea of who I am talking about...he tends to be a bit too conservative for my tastes, but he's certainly a good person).
Personally, I would have thought that character were more important than speech impediments, manner in which someone laughs, and culturally influenced idiomatic constructs...but what would I know.
It sound to me like the real problem at hand is something called education and affluence, my family may have come from the backwoods of Kentucky, my great grandfather may have lived his live as a vagabond, but my grandparents and parents made something of themselves, and I managed to acquire an education. The net result? It is no longer necessary to conduct oneself in the manner of an uncouth neanderthal to be secure in their sexuality ('Ugg strong, Ugg manly, Ugg tough, Ugg fertile, you not like Ugg, you not man.'). This is the 21st century, cultural norms have evolved for both men and women. A woman who is not strong and independent is simply not respected, likewise a man who is domineering and belligerent will be ostracized from polite society. It may seem that women are expected to be more 'masculine' and men more 'feminine', but ultimately a single standard of rationality is applied across the board; and the emotionally influenced extremes of gender dimorphism simply do not cut it anymore.
As far as the 'white trash' I wouldn't worry about them too much, the underclasses are generally a couple generations behind the rest of society...they'll catch up and become accepting of our (post-)modern cultural norms in a few decades. However, if we cater to them in the here and now we will alienate the driving segments of our culture and will be turned on by the current underclasses when they catch up in a few decades time.
