I don't think we're any more individualistic than any other society.
Self care matters. If I break my mental health by prolonged neglect of my social needs who puts me right? Oh yes I'll be contacting my NHS GP for anti-depressants. #SaveTheNHS.
I'm not having wild parties. Had one cluster of people in my home once, legally, within the rules, windows open to hold a youth group planning meeting. But I am overlooking surplus children on a walk because while it falls foul of the law, it is less morally wrong than leaving one at home to not exceed an arbitary number dreamed up by a bunch of men who don't spend much time parenting their offspring.
I get it. But I'd really like my DCs to see their family at Christmas for the first or second time in 2020. Some relatives they haven't seen in over a year now and it could be 18m- 2years by the time travel arrangements are practical.
I'm not refusing to put on my own mental health oxygen mask so that "Cynthia" at 8 chains of separation doesn't end up in ITU critically ill when any infection over this winter was likely to overwhelm her immune system. Viruses spread. We didn't have this outcry in 2018 when there were 50 000 excess deaths caused by a bad flu season and poorly matched flu vaccine.
It's at best pointless moralising over this, and potentially harmful when catching a virus is seen as a stigma and encourages people to cover up if they are mildly ill.
It's been dragging on for 8 months now with no end in sight. People have to live sensibly about it.
