Thanksgiving Rant About My Stubborn Religious In-laws

Why do my in-laws force their Catholic views down my husband's throat and my own? We have stated that we are of a different religion and now we are alone for thanksgiving because we refuse to convert. Has the human race really not surpassed this intolerance? It is so frustrating! Thanksgiving is not even about God! It is about Americans coming to America. Which we stole from the Natives, raped them, murdered them, enslaved them, oh and tried to convert them to Christianity. There is more than one lifestyle. That is one good thing about America. IT IS NOT A CHRISTIAN STATE! I can be what I want.
