Of course, "real men" can be just the opposite, depending on who you ask. So, it's really a subjective issue.
I don't think every man should be like that, but I also don't think any of those qualities are bad. In fact, I think they're pretty admirable.
Do you have issues with the fact that some men conform to that type?
Being able to provide for someone is an admirable quality, man or woman
Same for being able to protect someone.
I don't think being emotionally restrained is a good thing - and I say this as someone who was raised to be emotionally restrained. I've had to specifically work as an adult to be less emotionally restrained. I think there's a very wide gap between being emotionally restrained and letting emotions rule over you.
