I did a little analysis of two recent emails sent out on the list by the same sender. One email was in response to a male and the other to a female. Both emails were on the same topic and sent within a few minutes of one another. 

The male to male (MM) email used the second person "you" and the first person "I" in a 1:2 ratio. 

The male to female (MF) email used "you" to "I" in a 1:3.6 ratio. 

The first paragraph of the MM email directly addressed the previous email by a male academic.

The first paragraph of the FM email reiterated a point that the male writer said previously, something that occurred more than once in the FM email.

The MM email contained:

 one instance of concern trolling
one instance of an off-topic remark

 several instances of aggressive wording. 

The MM email contained no obvious typos.

The MF email contained: 

one instance of antagonistic wording

at least two instances of passive aggressive wording

two instances of concern trolling

three instances of questioning the female list member's intellectual ability (aka gaslighting)

two off-topic comments (one of which containing offensive and dismissive language)

one instance of what could be perceived as a veiled threat. 

The MF email contained multiple obvious typos.
