Am I wrong?

I just got caused out and told I was wrong because I don't think mothers should celebrate father's day. I'm not trying to cause drama or get bashed I just honestly want to know what others think. I understand that some dad's walk our on mom's and they end up doing everything but that is what mothers day is for. Single dad's can't claim mother's day so why do moms? Am I wrong? Please respond. Seriously curious if it's just me.
