This definitely happens! And not only when you see women gambling, but even when you learn about someone that a woman you know is into gambling, it immediately casts a certain aura of a slightly flighty or not quite feminine woman on this woman. It must be said that this is a red rag for a huge number of men. But of course, by and large this is unfair in the modern world, but nevertheless it is so and women should take this into account.
In my opinion, having more women gambling is something worrisome to me. I know many have tried to associate all of these kind of discussions to religion and religious beliefs, while I will also take that into account, that's not just the only reason why I don't seem to be comfortable with having more women flooding the gambling industry.
When are naturally fragile and emotional in their character. When you bite a man for the wrong decision he made, he will grumble and let go of the situation, but if it was a lady, she will cry all day and keep such event in her mind reflecting on herself and living the scars with her for a long time.
Having more females than males in gambling is something the society where such thing is happening has to be ponder about. Gambling is an activity of financial risks and when a woman that is meant to be the assistant to the husband and the family is now gambling to feed the family and take care of her needs, in that case something might seems wrong. It is not that women are meant to gambler but it's about the risk it could pose to the entire family as time goes on. Just imagine a mother using the fund that is meant for dinner for gambling, it means something is wrong somewhere and if it continues, problem could emanate where the children will have to fend for themselves anytime their mother incurs loses in gambling activities.
