The UK is a country where the Prime Minister may very probably have to resign because he is unpopular. See also Liz Truss and Boris Johnson. Prime Ministers in the UK don’t usually last that long if the public turns against them. Compare to the US, where Trump is deeply unpopular but also in an essentially unassailable position as POTUS. If Keir Starmer, or any other British Prime Minister, gave one press conference where they attacked a female journalist instead of responding to her question, and then criticized her for not smiling enough, they would be out of Downing Street within a day. So no, things are not going “just as badly” in the UK as they are in the US. You’re comparing general problems of discontent in a representative democracy with a total breakdown in standards of public life.
I’m not sure exactly what you mean by Brits “voting against the status quo”. That’s what happens any time you change from one party to another in a democracy. Wouldn’t it be more worrying if everyone kept voting for the same party and same policies all the time?

Gordon Brown did an interview with a member of the public and forgot to take his microphone off when he got in the car. He said (in private) he'd just spoken to a biggoted woman. That was broadcast and it lost him the election.
