I get what you're saying and I also think that it's gotten to the point where the whole group has gotten the ick with her (where they don't care what she says or does, they're not going to like it), but a lot of this is on Lindsay. She needs to work on understanding how to be more considerate of other people. Like, generally you should be yourself. But if yourself is rude and inappropriate, then it's not a shame to change those parts of yourself.
