I’m not “Wolf” but I can offer my “two cents”. Its not YOU its THEM. It really isn’t your issue and it never will be. People who put up a fence or a draw a line in the sand will always be that way. Either they were brought up that way or they just don’t know better. There is nothing you should do or could do to change that. The best thing you can do for yourself AND your family is be yourself. Enjoy what you choose to enjoy. There are plenty of Jewish artists as well. Hashem gives everyone different gifts and different talents. So if he gifted you with an eye for art or music, then you are lucky to be the receiver of that gift and don’t ignore it or take it for granted.
The only ones you need to please is Hashem and yourself. Everyone else are really not as important. As long as you are following Hashem’s wishes, you are not doing anything wrong. If you ask a question of a FFB and the best they can come up with is “because that is what WE do”, the reason probably is because they don’t know why they do it.
THEY are not better than you. YOU are Hashem’s child the same as they are. And you have to give yourself a lot of credit for giving things up to be who you are today. It is so much easier for “US” to be FFB. We don’t know any other lifestyle. It is not so hard “not to do” what you are NOT used to doing. But giving up things that was normal to you, and choosing not to do it is a remarkable sacrifice and understandably a difficult thing to do which is something that should be respected and not shunned or looked down upon. To put it in simple terms. It is not difficult to stay skinny if you were always skinny. But it is much more difficult for someone to give up their old habits and all the foods they love to be as skinny as everyone else and maintain that knowing how good those things tasted and felt to them. I can remember before I married having my hair flow freely in the wind. That was a wonderful feeling that I can no longer experience for the past 36 years. There are many times when I wish I can rip off my sheitel and feel that way again, but I can’t.
You made a decision to give up an old lifestyle that included many things that you loved to embrace a new lifestyle that you love. But that doesn’t mean that everything in your past was NOT kosher. Please make sure that you don’t give up permissible pleasures and then come to resent that. That is NOT what Hashem wants of you. And please don’t measure frumkeit by the standards of those who choose to judge you or make comparisons towards you. That is NOT what Yiddishkeit is about and it is NOT what Frumkeit is about. Those who do that can learn a few things from the BT community.
