So are you talking about online or in person? If you are talking about online, then I hate to be the bearer of bad news, but that is any forum these days. Hell, I bet if you found an 80 year old Ladies Quilting Forum, you'd still see Dixie talking trash to Francine. But, I bet if you went to one of their quilting meets, you'd see that they are friendly and welcoming, just like your grandmothers.
I've met quite a few of the people here in person and have been to a number of large comps and every person has been welcoming and willing to help and advise anybody that had questions. Heck, most competitors will spot for each other at comps.
Dont judge a faction of RC by the way people act online."thumbsup"
