Suicide party sounds like a great idea. However, there is a danger. If population is polarized (like US-style) and this new party will seem to be taking a side, party's image would be ruined for people who take the other side. That creates a risk that ideas you bring will immediately look bad for people on the other side because these ideas come from your party i.e. their opponent. But maybe it's not important, as long as ideas are now being discussed.

I was born in a country so corrupt and backwards that such a party would not make a difference.
