A regional party can have like 6-8 times more representation than a national one with the same amount of votes nominally speaking.
It is legal, but makes no sense, more so taking into account that independentist parties are forbidden in Portugal or France and that here they not only are allowed (I can agree with that), on top of that they can oresent themselves to the national parlament and do national politics when their interest is to break the system (I do not agree with that).
The law for overrepresentation was done to not smash minorities. However, what is happening is the exact opposite: minorities are driving the majority of people instead. Which is even worse and a privilege of a few over most.
Anyway, I agree that having 50 general election districts (one per province) results in skewed votes. This was done by design as an attempt to have an easier-to-control two party system, and enshrined in the Spanish constitution, so it's not easy to change. It's probably easier to change provinces themselves than the constitution in the current political climate. For instance, merging all provinces in each region together would solve most issues with the voting system, as it would increase the amount of seats in contention.
Regarding the argument about this being a government by a minority of people: the parties that voted for the current government represent roughly 50.5% of the total votes. The current opposition parties represent 45.6% of total votes.
Any midly-responsible governor would have, no matter how much some people dislike it, fone a deal between PSOE-PP.
I do not vote myself BUT this is what looks more sensible, political tendencies apart, for stability: only two homogeneous groups that represent a big amount of the population. Even if I do not feel represented myself.

This is not true at all. Search for corsican auto-determination. France actually has even allowed auto-determination referenda for DOMs in the very recent past. Certainly it's not exactly the same and I'm oversimplifying (many simply want to get rid of these regions), but please stop pointing fingers to France; you may realize we are not as different from Spain as you think.
It is a far better outcome to seperate through political means than by uprising.
Could say exactly the same about the socialist party. Or any other party, really.
Also: the party that you call right wing is as progressive as the socialist party. They have never done and will never do any change that is not progressive. Last time they were in power they raised taxes, did nothing to the homosexual marriage, abortion, and domestic violence laws, etc etc.
They may not seem extreme to some people, but that only says something about the political leaning of those people.
This is a matter of perception. Far right is isually (literature) described as right, violent and collectivist (facist) wing. Which by the way is quite similar to communism, just with a couple principles changed if you analyze it seriously from individual vs collective rights. How "far right" is used in Spain and a lot of media is not like that at all. Far right is España 2000 and Democracia Nacional.
> They may not seem extreme to some people, but that only says something about the political leaning of those people.
Again, that is your perception. Your perception comes from the status quo, and seems reasonable from a social point of view. However, when the media uses a term incorrectly and politically so often, then it loses its meaning.
That is why it is a good thing to know what we have in front of us and call it by its name. Otherwise all words end up losing their meaning. Far right is often not what most media calls far right by standard literature terms. Maybe by propaganda terms. But even Popular Party or Ciudadanos was tagged as far right sometimes. That's just the political tagging game.
I'd rather see what parties propose rather than qualifying them as something. I think it is more useful for everyone.
The current Spanish government is a very fragile minority, but it was voted by 7 out of 9 party groups in Congress (that is everyone except the right wing and far right parties), and the executive power has people from five different parties. Quite exotic for a dictatorship indeed.
