I believe it. I can remember many a times when GKs in front of 101 were rattled.
There's a HUGE difference with in-stadium atmosphere between Supporters Groups that are family friendly and those that are there to rattle opponents. One of those is fun to me, one of them is not.
I always felt we had a very open and accepting section to anyone that wanted to join. If you came to 101 and were willing to sing...you were instantly a brother or sister of 101.
1st paragraph: Yup. Fun times shitting on GKs.
