Toxic masculinity

So in order to find something to discuss about the terrible shootings in both El Paso and Dayton, the CBS news is discussing the heroes during those incidents.

Despite trying hard (I am sure), they were only able to come up with men who did heroic things in an attempt to save the lives of others. 

No woman, no flagrantly gay men, no lesbians, no transgendered folks (at least none who identified themselves as such)…And I am sure that the Media tried very hard to find someone.
Only men who risked themselves for the lives of others…often strangers.

Look: This was a tragedy. These folks perpetrating these attacks are whacked, deserve to be killed like rabid dogs, and (obviously) are mentally deranged.

I’m not trying to denigrate those other people here….those who took cover or ran did the normal thing….the wise thing. Those, however, who tried to save others, are heroes. And so far, I haven’t seen anything but men being hailed as heroes in these incidents. Why is that?
