No, we don't agree on this. Not at all.

For every thread you can find where someone was dumped with honesty but preferred tact, I can find a thread exactly opposite.

We just had several long threads where people desperately wanted eH's match closing process to allow for write in answers, because they claimed to want the advice. (From people they never met and never even communicated with.)

Face the facts, unless you tell your match in advance how you would like to be dumped, you're probably going to get dumped in a way you don't like. That's life.
