It's not hard for anyone to get into stalking, male or female.
What is difficult for women is working their way up through the ranks once they've started, particularly if they want to do it professionally. There is a general assumption (as seen in a few comments on here) that they won't be capable, or strong enough, or too squeamish, or whatever, and it's a real struggle for them to shake off this prejudice.
They prove time and time again that they're just as capable as their male counterparts, if not more so. Yet still the prejudice persists, making it harder for them to gain employment in the sector (or simply to be taken seriously, if stalking recreationally).
And then there's the whole risk factor, perceived or otherwise, associated with going on (or, later in career, guiding on) paid stalks. There are a lot of lady stalkers who start out but make little progress due to the - understandable - fear of having to meet up, alone, in the middle of nowhere, in the dark, with an unknown bloke with a rifle. You say they're welcomed "with open arms". Perhaps that's exactly what they're afraid of? Same applies to doing DSC2 witnessed stalks. Which is one of the reasons why Mouse is now an AW - so women who want to take DSC2 can have a female witness if that makes them more comfortable.
I think it’s very hard. FAC, DSC (or PDS-don’t get me started there), mentors, and that’s before you start looking for your own land, which is a nightmare.
I have worked in 2 traditionally male dominated industry’s in my career, and as a result of changing times seen women fast tracked at every opportunity. I have, to my face, been told not to apply for at least 2 job opportunities as I was the wrong gender. Don’t get me wrong, I’m not complaining as I know how things work….but I feel that traditionally male orientated roles are crying out for diversity, let alone creating extra barriers.
Your last point, if that’s an accurate, commonly held perspective I find it quite depressing. I can understand the sentiment but it seems a slight stretch….but then I’m not female so I really can’t comment.
