While I agree you shouldn't have been kicked because of your gear, you didn't give the GM any real information besides "I got kicked from this party". Did you give them any names, time of day? As a side note, do you have any proof they were running a parser? Just because you were removed does not mean they were using one. You're allowed to be upset over it, but remember to not let your emotions get to you and say things that may not be true.
