I work in tech and some of my male coworkers privately tell me that they avoid talking to womens they don't know at networking events or at conferences because of the way it might be interpreted nowadays.

I also think that it's easy to get sucked into circle-jerks that promote and exaggerate these fears of being accused of harassment. As long as you're considerate and respectful, no reasonable person would think you're harassing them. There are always unreasonable people, that shouldn't divide us into men vs women, into groups that fear interacting with each other.
