I wouldn't say it's ONLY tech that is talked about here, I do see a lot of cross-over with Tech and the political climate in the United States as both are very much intertwined. I have seen people recognise that things are becoming a lot more autocratic.
Though for your sanity, I recommend trying to pull away from the news and social media much as possible. These places greatly amplify the issues and no doubt make people more anxious and nervous, because they want your attention on their platform all the time to advertise and make revenue.
It's important to stay aware of events, but you gotta make sure you take care of yourself too. Take a break if it's becoming too much.
As for what to do about the US... I can only hope your constitution and those who truly uphold its values will continue to fight the attack against it.
