I have found that having a talk sometimes helps. I make the tone pleasant and tell them all the time and effort I have put into living my life in a way that means everything to me.
I go on to explain that I can understand people see things differently, and add there is no way I can show you all the steps that lead me up to my beliefs today.
I finish by saying it upsets me to hear these generalized comments and that, in turn, I hope I am not saying or doing things which offend your beliefs.
Usually, this helps. People dont want to be mean face to face. They just end up politicking and fall into a role.
Hatzlacha Rabbah!!!!
