AITAH for not wanting to baptize my daughter?

This year, my wife (27 F) and I (29 M) had our first child, a daughter. Of course, we are overjoyed, and the whole family congratulated us. Everything was fine until my great-aunt's birthday. The party was a typical family gathering with aunts, uncles, and cousins. Everyone talked about what was going on in their lives and, of course, asked about our daughter. Finally, one of my aunts asked when we were planning to have her baptized. I replied that we didn't want to baptize her. After that, the room fell silent. You see, Poland is a very Christian country and most Poles are baptized, including us. But as adults, we don't think it's necessary, and if our daughter wants to be baptized when she's older, we have no problem with that. My family disagreed. Immediately, accusations flew that we were terrible parents, that it was our duty, what people would think, etc. I saw no point in arguing with a whole room full of people, so we left. Two days have passed and we are still receiving messages from them about how terrible we are. Even my parents are not on our side. They suggest that we have her baptized just in case something happens, which in my opinion goes against the idea of sincere faith in God. If the situation doesn't calm down, I think we'll have to cut ourselves off from our family... what do you think?
