I have Tourette's as well. However, based upon what I read from the OP's post, mine is far minor in comparison. In fact, when I do tic, many folks think I am sneezing.
Now, in addition to that, I have worked with kids with autism for years. Another population that some don't like to see at the theatre because they can be disruptive. Now, while I am fully in support of the TDF's autism friendly performances, those with Tourette's or other cognitive issues that can't be controlled should not be relegated to just those performances. And, these are people who have to go through life who were dealt a bad hand. I know that we talk about issues we face with things such as cell phone use in the theatre. But, when talking about another human, I think that compassion and understanding is not hard to do. Put yourself in their shoes. They don't want whatever it is they are dealing with and it's not like it's they have any say on the matter.
This reminds me of a facebook post I read a few years back, when LCT was doing The King and I. During the whipping scene, a boy with autism, who, up until then had been quite and causing no disturbances started to vocally act out, gripping on the hand railing to not leave etc. Now, there were a lot of posts on Facebook etc about how, someone like that, should not have been in the theatre in the first place. However, one of the actors on stage in that scene wrote on social media that he was beyond happy to see him there and felt bad for him that he had to deal with that. Thereby going his fans the opposite response they thought that they were goin to get. Show some compassion and understanding, Yes, money was spent to enter a venue, open to any and all ticket holders. Deal with it.
