None. I have far too much self-confidence to be scared off for that reason. I can deal with the frequent disagreements but it took me a looooong time to become comfortable with that. I was people-pleasing and at first I couldn't tolerate the experience of causing or persisting with disagreements because I didn't like making others uncomfortable. I had to train myself to deal with that but I'm good at it now. I have to wonder how many other women would find it hard to put themselves out there and take all the resulting criticism. If women often have a preference for supportive environments, that may be part of the reason for the gender ratio being skewed.
