Wait, how come you don't know who Alexandra Kollontai is? I'm not even anything left leaning and I know about her and her works. And yes she does have very good point, as do a lot of communist but still paints an image of communist and family. Here's a good example:

Working mothers have no need to be alarmed; communist not intending to take children away from their parents or to tear the baby from the breast of its mother

That's fair, yet a few lines bellow:

Society will feed, bring up and educate the child (...) Communist society will take upon itself all the duties involved in the education of the child

So you start by saying that the communists don't want to take children away but then proceed to bring up and educate. That's kind of suspicious.

To be fair, that could've even been true at some point. I see that a lot of the communist ideologies only work if seen from the right angle (ironic) and with good intentions, however what are really communist groups and parties nowadays?

Half of those groups got mixed up with the gender/identity bullshit people - those who end up yelling to politicians about children not getting free gender conversion therapy and whatnot. Those communist groups/parties groups/parties that don’t particularly share their views but agree to “bite the bullet” just for the numbers. Numbers are all fun but this will eventually backfire once those same groups lose their true ideology / identity and become associated with those people and lose all their credibility.
