I'd go as someone's guest and see if things have really changed and then make a decision. I think this is a common problem for guilds, as you are not the first person to describe this kind of vibe at a guild. I have had a similar experience to yours as well.
What's more fun is to start a small quilt group of your own, limiting the membership to a manageable number. That's what we did and we're all very happy. No politics, no gossiping, no cliques.
