What you think is the real reason people don't appreciate muscles on women?

Iam not seeking here for any validation about me and my partner. But trying to understand the mindset. If the peoples opinion is based on their society or the background they come from.
Following are the reasons i found with personal experince after interaction with people and their comments and reactions.
1-----They have their won beauty standards degined for women in their mind which do not match with a muacle women.
2---- They feel threat to their musculinity when a women is stronger and has muscles.
3---- They just go with the society sterotypes amd never give a thought about it.
4---- It hurts their male ego and think its embarressing fot them and are scared of society reactions and comments
