I don’t even know where to begin with your post!
I will preface this by saying you will read my post and just think it entirely confirms your beliefs. So I’m on a hiding to nothing, but nonetheless...
I’m the same decade as you, but older.
I don’t see anyone as a threat, and if anyone sees me as a threat, it blithely goes completely over my head.
The women at work who are my age are friendly and chatty. I have never noticed one discernible difference between the women my own age, the women younger than me, or the women who are older than me. Not one.
I put it to you, that perhaps the issue is you (see my comment above where I state that this is where you will think I’m being mean, and it just confirms all your beliefs).
And finally - not once, ever, have I ‘mollycoddled’ a man. Not my own husband, and certainly not a male colleague at my work place [shudder] 😳
Your comment suggests you wish to be mollycoddled, and you’re feeling short-changed that you’re not. Again, I therefore suggest that perhaps the issue lies with you.
