We kind of agree with you. For example: Mother's and Father's day seem like obligations, especially for shitty parents.
If someone is a good parent, they do not need them. If they are not then it's just a way to force your children to give you things, submit to your authority and make you feel good about your shitty parenting.
If it helps at all, where I'm at, it's known as 'day of the feminist fight'. And it's about commemorating the wins that feminism has already had but also marching and being angry at all the gender based discrimination that still exists. I as an nb personally love it. I know you won't be able to change how the day is viewed around you and how you're supposed to act on it, but maybe mentally you can see it as a feminist fighting day? Idk if that helps
For me all the "female" stuff is just FINTA stuff instead. Easy fix and conservatives don't really know what FINTA means so they don't care and I can celebrate alternative gender identities in peace.
