Weapons sales are besides the point. There are plenty of corporations doing totally non-shady things that make exactly the same kinds of tweet. I don't think it's helpful to drag this thread into a discussion about the ethics of selling weapons. I suspect that we don't even disagree on that point. (Please don't think that I hold any brief for Raytheon.)

I find the rest of your post a little bit confusing. I don't think you are saying that you want Raytheon to stop making tweets in support of LGBTQ rights. But also, you seem to be hinting that there are somehow potentially bad consequences arising from Raytheon, or other corporations, making these sorts of statements. As the bad consequences are only sketched in the vaguest terms, it's difficult to know what to make of the idea. For example, you seem to suggest that people might be more alert to the bad things that Raytheon does if they didn't publicly support their LGBTQ employees. But you don't have to wind back the clock many decades to get to a time when they didn't do this. It doesn't seem that people had much more success in compelling Raytheon to stop making arms sales in the 70s or 80s than they do now.
