You aren't helping your cause. The "he/she" crap is cumbersome and annoying. You are trying to promote a product. Annoying people is not a good way to accomplish that objective. Mitchell has a name: it is "Mitchell." Unless you know a lot of girls named Mitchell, it would have been safer just to use the masculine pronouns. Or, if that offends your sensitive soul, just use his name. For the possessive pronouns, you could substitute "Mitchell's." Similarly when it is the subject.
Mitchell is one of the more knowledgeable and assertive members of this forum. (I don't want him to know I said that, which is why I am posting this in invisible ink.) So, you came here to promote a product, and you got your feathers ruffled because Mitchell called it "crap." Now you have a choice. You can:
a - Pursue your original objective and find a way to promote your product, or,
b - Get all pissy about it and engage in a no-win contest, wherein your original objective is totally lost.
The choice was, and perhaps still is, yours to make.
Wow, do you actually hear what you're saying?
He/she is cumbersome and annoying...you have got to be kidding me, or did you really just use that as a point of a rebuttal?
I thought the community here was much more friendly and professional...
