You most likely are arguing with a right winger from Spain. They compare the president with a dictator in their right wing media, and they basically talk about Spain like is Venezuela at every opportunity.
I totally agree with you, but is not just the progressive views on gay marriage on the EU that are at risk, is any progressive thinking. There's a wave of right wing backward thinking around the EU, and we keep adding more countries like Hungary.
This doesn't make sense. We're admitting another Hungary in our club, and this is not going to end well. Any progressive vote is going to be blocked by those countries, and we're going to be paying money to them to vote our way as we are doing now with Hungary.
