I never judge anyone solely on what they do. I have had friends that were both dancers and outright prostitutes, both types had kids. Not by me, nor at their own homes of course. Even known a porn star once. Not that I ever knew her as a friend or do anything with her. Though I did grieve for her when she miscarried. A close acquaintance let's say.

They were all good people and or good parents.

You are doing a fantastic job raising him. Idc what you do for a living...you are doing what you have to do to make ends meet and take care of the 2 of you.

People are often very close minded and judgmental.

Sounds like you do well

Fuck them... Just turn the other cheek and keep doing what makes you and your son happy.
