First, to say that the two majoritarian "independentist" parties, ERC and Junts, haven't done much at all lately. They've used elections just to get into power, get salaries, and then keep the status quo, making pacts with parties that, in theory, should never agree with them like PSOE/PSC and PP.
These two other Spanish parties have responded by betraying them at any chance too, so it's really really stupid that ERC and Junts still try to pact with them when there's solid proof their word is worthless and they will not fulfil what has been said. Although Junts and ERC are also very very guilty of that.
So, people are pissed at these two independentist parties. The third big one, CUP, has acted much better in general while not being perfect, but has been added to the group for some reason(even though it never had enough power to act on much), maybe because people, once they distrust their original choice, apply the thought that "the rest are the same" when it's not actually true at all.
So now, there's an undercurrent of thought that these three independentist parties must be punished. And way too many people have decided that they will punish them by not voting at all.
That's the stupidest, STUPIDEST thing I've ever heard.
For three reasons:
1-The less votes there are in an election, the more votes the right gets (and here I mean PSC/PSOE, PP and VOX. These three parties represent right-wing politics, from moderate on the first case to extreme in the second two ones).
Parties don't give a fuck that people didn't vote as long as they get representation.
Basically, if there's 100 people able to vote and only 10 people vote, let's say, and they vote 4-PSOE, 3-PP and 3-VOX, these parties will not say "oh, why no more people didn't vote". They will say "oh yes, we won a lot of representation, we're the best!". And they will do whatever the fuck they want. And it will be BAD.
These parties are the enemy of everything good. Simply put. Independentist or not, you should NEVER let these parties win at anything. If your actions are making their life easier for them, your actions are automatically BAD.
2-Not voting doesn't give any power to your cause.
If you want to change things, there's two options, revolution or voting for things that represent you in some way.
To all these people that don't vote: will you automatically take arms and start a revolt in the streets? No? Then what you're doing is harming your cause.
Nobody, nationally and internationally, gives a fuck about why you didn't vote. They only care about the people that voted. It's been proven time and time again. There's been lots of elections in the world where for several reasons people didn't vote that much. Nobody has ever commented. The final results were the only ones that counted, and that was taken as "the will of the people".
I totally agree not voting should be considered as a bad sign. But nobody cares, so not voting will be ignored, and if something it will be considered as a fact that "independentism has lost strength, nobody wants it anymore". So, do with that what you will.
3-Dont vote for the parties that you don't like, but change your vote!
It seems like once there's a party that is yours, it's them or death. If they don't do a good job, lots of people stop voting altogether. A lot of people didn't change their vote from ERC to Junts or CUP or some other combination of this, they just stopped voting altogether.
This is stupid! You don't like your last vote? Change it!
If people don't vote, less votes means more representation. Let's say that you have 10 people voting in total. 5 vote to ERC and 5 want to punish ERC. If the 5 that want to punish ERC don't vote, ERC gets 100% of the votes, so 100% of representation ->great success! We're on the right path, people love what we do!
Do you want that?
If instead, the 5 people that want to punish ERC vote Escons em blanc, CUP, PACMA, anything really that is not ERC, ERC gets 50% of representation ->they're punished.
I will concede that there may be not many options available that seem good. But not voting will do NOTHING whatsoever to help you or your cause.
See what the right-wing parties do.
They never, ever, miss a vote. That should give you a clue.
