Granted your argument would have more weight if say 10% of the population voted, but with 40+% of the population voting you need to accept many yes and no voters stayed home out of fear.
Or more widely if their where much doubt the government would have let a vote take place secure in the knowledge they had popular support.
Who is making this report, why should I trust them, and do they have evidence this is a statistically meaningful problem?
However, the exact same thing would be reported if it did not happen making it somewhat meaningless observation.
PS: I really don't trust the 90% yes either. But, vote suppression IMO is a sign the people in power expect the vote to go counter to their desires.
Modern societies should be flexible enough to allow for friction-less changes: there are no holy cows.
The first part, the feelings, I can't share but I can respect. I don't think it makes for a significant part of Catalonia though, maybe 20-30%? The second part, the in-solidarity, I can't have simpathy for and I think Spain is right in staying put. And if that's the part that is really moving so many people to independence (and it seems that way), then I don't think this is so much a matter of opinion as it is of not knowing or not respecting the facts.
But this is not the only issue: the situation in Catalonia is complex, and ultimately should only be decided by Catalan people. One of the most common arguments against the referendum, namely that people are being "brain-washed", assumes three things wrongly:
1) That brainwashing happens only in one sense.
2) That people are easily brainwashed.
3) That brainwashed people have no right to vote.
The Human Right of auto-determination does not only apply to societies we are not directly related to, but specially to the cases where we have an interested stake, since that shows that we are actually committed to those rights, and not using them abstractly to control remote regions by UN proxy.
The general principle applies: "I might not agree with you, but I will always defend your right to voice your opinion"
edit to attach the sentencing in particular, it's perfectly legible (only 14 articles eliminated), and the reasons why they were excessive easy to understand.

Criminalizing a vote – to the point of beating people – is beyond stupid. It strengthens the cause for Catalonian independence. It only makes rational sense if the Spanish government is very afraid of what a "legitimate" vote says.
