This can be true, but it's not necessarily always so.
Many years back, my partner was sexually assaulted, so I attended a few of her counseling sessions with the local Rape Crisis center as a support person. The female counselor commented that I was "very brave" to do that - something I found very odd.
Years later, my partner said that the sessions I didn't attend were little more than "man hating" and "man-blaming" for all of the world's wrongs.
I have also attended counseling, as I've recently started to understand the level of physical and psychological abuse that was inflicted upon me by my mother (and her boyfriend, as well as my stepfather) while I was growing up. My counselor was also female, yet not once did she belittle my suffering as less because of my gender. As I described a few events, I'd even hear her let out a gasp or draw a sharp breath, or a few words of concern.
It seems possible to me that you've come across individuals with their own concerns and agendas that lie outside the requirements of their jobs, but I couldn't write off an entire profession based on that.
