It would help if third parties would do something other than put a candidate up for President every 4 years, fail, and then disappear for the next 4 years. That's a waste of everyone's time, money, effort, and votes. Parties that do this should be looked on with suspicion.

Get people into city councils, school boards, and county comptroller. Work up to state level government. There is tons of good to be done at that level of government--in many ways, far more than the White House could ever do.

Greens, this is about you, specifically.

All you do by voting for a 3rd party in a FPTP election is take a vote away from the major party you are most closely aligned to. You may as well just not vote

Then you might as well not vote. This is not the right political climate to try to make 3rd parties viable.

Unless, of course, you want the country to become a fascist theocracy.

Our viable parties are shit because our electoral system is shit.

The 100 year path of wishful thinking that single person who votes will suddenly change their behavior such that they won't vote strategically hasn't got us anywhere. Our electoral system needs reform. It is inherently biased to make 3rd parties fail every single time. The game is rigged for 2 parties and only 2 parties.

and then just completely ignore that their view is led

You're talking about a view different from mine.

our liberty and economic power has dwindled progressively with each passing election

That's as much a consequence of legalisms - Bush v Gore invalidating votes in swing states, Tom DeLay kicking off a big wave of legislative gerrymandering, candidates party-flipping starting in the White Flight of the 80s/90s (WV's governor flipped the day after the '17 election), the banning of earmarks in legislatures and the legalizing of unlimited campaign donations following Citizens United - as voting patterns.

So much power has been consolidated within the hands of party leadership and so much money has flown to affiliated party-loyal business interests that voting no longer shapes political behaviors. When Republicans can't win an HISD board seat, they turn to the governor to simply take over the entire board by fiat. When someone in the Democratic Primary attempts to unseat an incumbent, the party spends tens of millions to defend them. When a third party bid emerges, they're cut out of debates and excluded from news coverage save for the yellow journalism designed to dismiss you as a crank. (And, in fairness, there are tons of cranks in the 3rd party scene already).

I don't think you can strictly attribute this to "not enough 3rd party bids". We have consolidated political power in the same way we're consolidating economic power.
