What about just calling people what they prefer to be called? If Rasmussen doesn't like "you guys" used in reference to her, then she is perfectly entitled to insist that people not use it with her. However, her feelings aren't universal, so why should everyone else change? So that she can feel better? That seems like a really weak reason, to me.
I really really really can't stress strongly enough how much it shocks my heart to hear how often the expression "you guys" is used in everyday language, especially in social movement/radical community spaces.
I don't mean to be unsympathetic or humorless or heartless. Yes I understand how difficult it is to replace that phrase with something else. But I promise it can be done. And talking about love and revolution and radical politics and building a movement feels so much better once "you guys" is gone.
This country consists of many different cultures spread out across a continent. Words just don't mean the same thing everywhere and I think it's a bit hegemonic to try and create some universal standards about what is and isn't better for all of us. I've lived on the West Coast, in the South, and the Midwest and I love the diversity of speech that exists in this country. Language is a significant part of culture. Each culture that uses a word adds their own meaning to it. It would be a shame if that diversity disappears any more than it already has.
I mean, what are we looking for? Is this what social movements are trying to move towards? A world where we all think and sound alike? If so, where does it stop? Personally, I'm not very fond of the word "b*tch". However, do I think that everyone else should stop using it? Nope. Is there any guarantee that if everyone stopped using it, "social movements/radical community spaces" would feel better for us all? If using the term "you guys" is problematic to Rasmussen, then how in the world does she square that belief with the fact that this is written in a magazine called "B*tch"?
In many places, these controversial words are colloquial terms of endearment. "Darling", "cher", "you guys", "girls", "folks"--it all depends on how they are being used. If my momma calls me up and asks "How are you guys doing over there?" it sounds a helluvalot better to me than if she asked me "How are you and the man and the female child doing over there?" It certainly wouldn't make me feel any better to hear the latter rather than the former. In that situation "you guys" would be perfectly fine with me.
Of course, since we're down here in the deep, deep south, we usually use "y'all" to refer to groups (of single or mixed genders). Still, is that really better than "you guys"? Better to and for who? I don't think any of my former English teachers would see it as much of an improvement.
Also, it's dancing dangerously close to cultural appropriation for some of these folks to start trying to switch from using the words from their own culture and purposely adopting the dialect of other cultures. If I'm in the heart of Wisconsin and some Mid-westerner starts using the word "y'all" to address a group that includes me, that would sound a lot more problematic, and perhaps offensive, than if they had just said "you guys".
