Come on, you must see there's a difference between dumping an unused car for weeks in a small cul-de-sac with only three available spaces and parking in a public road for a limited time when you visit a friend or relative?!?!!!
It's emotive language, referring to it as 'dumping', though. If the driver of a taxed, insured, roadworthy car parks it in a public space, why would you call that dumping? Do you dump your own car ever time you park it somewhere?
Do you really believe this?? Someone with a massive house and driveway, with multiple cars, is permanently taking up one of only 3 parking spaces in a small residential cul-de-sac where they don't even live, and it's OP who's out of order?
I think PP's point was based on somebody telling others how they 'should' feel to do something perfectly normal and legal.
People need to realise that the private houses on a street have no link whatsoever with any suitable parking that there happens to be on the public road adjacent to the houses.
I live very near to a park, but I have no more or fewer rights than anybody else in the town (or from further afield) to use the benches or equipment - it's public, for anybody to use, and entirely first-come-first-served. If I can never get a free bench, I'm not going to start demanding the postcodes of everybody sitting on them and telling them off for occupying 'my' park if they happen to live further away than I do.
