There's a supposition made in my yahoo group that Modern Orthodox people are more friendly and accepting of those outside themselves than yeshivish folks.
Well, I don't know if you guys saw my recent post (a post or so ago), I davened at a yeshivah for ROSH HASHANAH and sooooooooooo many people came over to meet me and find out where I live and such. There was a modern shul I went to for about a year in my own neighborhood where I used to introduce myself to people and I still couldn't meet people. They would look at me like I was from outer space.
Also, I think a lot of it has to do with how you dress. People who wear skirts ABOVE their knees would never be accepted in a religious circle. I know a convert who told me she wears skirts above the knees and it's ok if she wears pantyhose. That would never fly in religious circles.
It's interesting that I am Modern Orthodox and I have no problem WHATSOEVER with the Yeshivish community and yet Modern people don't accept me because I don't have the right kind of job or make enough money. They tell me it's Jewish to to have money. Therefore, I shouldn't have been converted because I don't. Somehow though, they seem to accept teachers in the modern world, even though they don't make much.
