The poster above is being down voted because they are not using the proper terms. What they are talking about is called sex, with gender explicitly being the socially constructed notion usually based on biological sex.

Further, they are using a bad definition of biological sex anyway, as 'people who can impregnate' and 'people who can give birth' is limiting (many cis men can't impregnate for various reasons, and no cis woman can give birth after a certain age, or before a certain age).

The rest of your own comment is low-effort claims with no connection to the topic at hand.
