I used to be worried at first. But having leveled not one but two tanks to 60, I like to think I've accumulated enough experience to do the job decently well. And, since I run through content as a healer first, I usually have a general sense of the fight - though there might be a couple tank things I'm unaware of.
Of course, no one can see that. And some don't even care and want to tell you how to do your job and get testy no matter what you do. I think I mentioned in the Vent Tent a little while back where I had to deal with a mouthy DRG that was completely abrasive and demeaning, and got snide when I told him that - while my character was new in the instance - I had run through it twice before on my other two characters.
Just do your best, and if someone is being enough of a jerk - initiate a votekick. Most likely, everyone else isn't like dealing with the guy either and it'll pass. If not, you can always remove yourself and find yourself a nice, new group with your <5 minute tank queue.
