If you don't want it to effect you, don't go to their house parties 🤷‍♂️.
You are still free to interact or not interact with people as you wish. What liberties of yours are being threatened by people having a house party? If people having a house party effects your liberties, wouldnt people unable to complete basic sanitation procedures because they have no water or electricity also effect whatever liberties it is that you are talking about?
It's not just the house parties, it's all the people blatantly disregarding any good practices for reducing the spread of this virus. I want this shit to be over with, every day people like this get together is another day (or more) I'm stuck at home waiting for it to all be over (my wife is doing chemo right now, high risk, so no choice on my part). You talk like they're stopping sanitation everywhere, let's face it, people won't get together at a house to party if there's no power/water, so it's a non issue, there won't be anyone lacking sanitation when they don't go to these places.
