The part about being pressured to post the statement about BLM may be true. Nothing wrong with pointing that out.

But then she starts to over-speculate about Armstrong's emotions without any basis and tries to frame him as an unstable person. All of this simply because Armstrong posted about his company's mission.

How would she feel if talking about her company's mission resulted in execs from other companies tweeting about her "having a meltdown", simply because she has a different political perspective?

She comes off, to me at least, as:

Unprofessional, ideological, dogmatic, crazy-lady

What specifically did she say that made her come off that way to you?

Spend a few minutes scrolling through her Twitter feed:

And on, and on, and on. She tweets so much it's kind of sad. Practically none of her tweets have anything to do with actual engineering. It's all identity politics and other leftist nonsense.

I didn't find any of those tweets unprofessional. I found them to be a genuinely interesting perspective on social issues that I am interested in. I am not sure how that's unprofessional of her.

If you think its "leftist nonsense", then that's just your opinion.

She is entitled to tweet whatever she wants to from her personal twitter account. Do you think its reasonable for her to follow your idea of how a Director of Engineering should tweet?

Why would tweets (from her personal account) need to be about engineering?
