I?m sorry
I am glad your parents are trying .
Wish they would stand up to them but she is being bullied so I get it.( different generation)
My dad =( RIP ) things had to be a certain way and no matter facts or anything else and sounds you have the same kind in your family.
Glad your younger ones are not going as the bigots do not deserve any of your presence.
Your kind words about your mom show your character.
I hope you do post how far your parents have one, just sorry they are not there yet.
With some they might never get totally there but hope they do.
Hold your head high.
Maybe have a get together with your kids , make it special and memorable.
