Oh Charaz sweetie, I am so sad for you that what should be such a happy time for you has been ruined by your pushy, emotionally abusive IL's.
He is YOUR son, and only you and DP alone have the right to name him, it is just SO WRONG for your IL's to have bullied you and treated you that way.
I definately think the best thing to do is to give your son a name that you love... perhaps negotiating on the middle name might be something to think about, but even then, it is totally your decision. I am so sorry that you haven't been supported in the way that you are entitled to.
Please take care sweetie, we are always here if you need to talk... I hope things look up for you and DH soon. :hugs:
