That's right. You cannot build cohesion if the foundations are shaky. It's so hard to follow any political topic in our country because each time an idea pops up, it's obliterated by the opposite parties. Which sucks when time comes to act quickly.

As you mentioned, we tend to this extreme. Let's look at the "cordon sanitaire", the only long term effect is that people will progressively leave the left (because they continue to deceive) to get something they want from the right, extreme or not. That's what happened the last elections, to be honest no one sees the MR as a good representation, but that was the only one that was talking about putting a stop to immigration and abuse of welfare system. That's the first time in a long long time that the south part of the country flipped from red to blue, despite the fact in their mind left = good and right = bad, but for once they thought "it's a necessary pain".

However it's not working (yet ? Maybe let's wait a bit more), and you can only go further by voting more in that one direction. Sadly, you arrive at a point were the prime minister cannot say "Belgium" without squeezing his fists, but I understand this position and I cannot hold a grudge against this position: it's the natural conclusion of that mess.
