Pretty fair view on astrology! I have some friends/family members who have very close birthdays and it's actually remarkable how similar they are in certain ways. I feel like I typically see the similarities in the way they handle things like relationships, power dynamics, confidence, and they sort of thing.
For example I know many Geminis, and one pattern I've noticed is that they are all passive aggressive types. Like they won't tell you about a problem until it's too late, and then they will boil over and you'll end up in a fight about something that could have been resolved so much easier.
Could that be confirmation bias on my part? Definitely. But still it's a fun tool for introspection if you don't take it too far :) I also like to think of the history behind it and how humans developed it in such a human way just from observations.
I don't take astrology that seriously, it's more of a conversation starter or a tool for introspection. Sometimes I see things about my birthdate that help me notice new things about myself, and sometimes it just seems made up.
Connecting astrology to anti-intellectualism is a pretty big reach in my opinion. I don't think the ideas of astrology, religion, magic, etc should be applied to policy that impacts anybody else.
