I meant it more as an analogy than anything else. I've seen the "but what about X" argument being used a lot lately where X and Y are the same issue that affect different groups and both are deserving of attention but one is more (maybe much more) prevalent than the other. As a means to derail a discussion of Y someone says "but what about X?" so a discussion becomes so broad and general as to be totally meaningless.
In this situation, rather than being able to focus on an issue that many women face, you end up in a discussion about all of humanity and genders and personalities that will likely never address any issue at all. I have room in my head to be concerned with issues that affect different people and talking about them in the context of one group does not imply other groups do not matter but some people act as it does.

I understand, and my post was a digression, but I felt it important because I was shocked when I learned the severity of the problem.
That being said, I'm not sure why you are getting downvoted but I've also found myself doing this accidentally and I've learned to moderate myself.
I don't think it is necessarily related to sexism directly, but I am used to talking to people (generally other men) who similarly assertive (not to say any of us are majorly assertive, just we're all at a similar level) and we understand each others speaking style and butt in (somewhat) at the appropriate spot to make a point.
When talking to someone who doesn't converse quite the same way (regardless of gender) it can be a problem. I've talked to people who won't just butt in when you are hogging the conversation and if you want to not have a 1 way conversation (ie, you are not an ass) you have to allow more space for the other person - its a basic courtesy and part of learning to have good conversations. My girlfriend has been helpful in self-identifying this situation because if I'm overly excited (coffee often being involved) she'll straight up tell me rather than putting up with it and I'll realize I was kind of rolling over her unintentionally.
I have no idea if this guy is sexist or not, it may be a subtle deep rooted kind or it may be he's a terrible conversationalist/host but despite the fact that this situation probably occurs more frequently from men to women but its definitely not limited to that.
