if i were to pug, i'd check the characters to see if they're from the same guild. usually, this helps out a lot as many guilds have great players and only need maybe one or two folks to fill in the gaps. however, if there was abuse like what you were getting, i'd drop group and work on something else. there's nothing you can do about idiots who measure your value based on your gear besides let them be.

what baffles me is that they'd be making fun of the healer... i mean even undergeared healing is much much better than no healing at all. which is also what i said to my other pug last night who wanted help with an outland instance. i got on my feral druid (80) and told them that hey, if they want heals, i can heal. but if they dont want me, good luck waiting another hour to find a healer (i was helping out a friend in the group). i ended up going and got annoyed at them (all DKs, would you believe it?). instead of dropping group like i could have, i told them to let me tank, w/o healing. we breezed through that no problem. i think it was sethikk halls. one guy kept dying, people got their gear, etc. but it was still rediculous to me how if somoene who can heal was willing to heal, why would they even ask for qualifications? some healing is better than no healing at all.
