Genderalizing our son. Sorry it's long. But someone please shed some light on this.

I posted a few days ago about this in general pregnancy. But since then it's becoming a bigger issue with my mother in law and sister in law. I just can't seem to understand this at all.

We just found out we are having a boy due in November. My mother in law and sister in law said they are still dressing him in the girl clothes and dresses they bought (because they went out and bought a ton of clothes thinking it was a girl). My husband said absolutely not and I agreed. They called us horrible for genderalizing our child because he could be gay and we are forcing him to wear boy clothes.... they are talking about an infant here. Am I crazy for being super pissed?? They literally called us horrible for planning to dress our infant/toddler son in boy clothes and not girly dresses. And they said that they would do it anyway any time they babysit, they don't care. We did say if our child made a decision to play with barbies or whatever, or maybe later in life told us he was gay or identified as female, of course we would still love him just the same!!

My sister in law has tagged me in Buzzfeed videos about genderalizing. They are continuing to tell us we will be hurting our child mentally by assuming they want to be a boy. I understand dressing gender neutral and what not. I can agree with that. But girly dresses? I don't see how that's right. They even are taking as far as we shouldn't be using blue for the gender reveal because, again, that's genderalizing. I really am at a loss. What do you do, not call your child your son or call him a baby boy? I understand he may make a different decision WHEN he is OLDER but I'm really frustrated with this at the moment. They keep saying we need to stop genderalizing now so we can have a world without gender. I'm just super confused. This seems so ridiculous to me. I don't want our son to feel we wanted a girl because his aunt and grandma dress him as one. I don't want to confuse him, I want him to be his own person but apparently dressing him as a regular little boy or as gender neutral is keeping him from that?? I just don't even know
