I see you switch from defending him (as it's impossible) to "both-siding" it, and pretending I have a "focus" on him, and then hinting that I'm just scared... Sounds like a typical LFI politician. It's disappointing.
So, let's start with "Why do I have such focus on Melanchon?"
That one is just dishonest. Let me remind you of your own answer that started this focus on Mélenchon:
"Not sure what Melenchon is doing in its list as one of it core element of its political platform is to have a new constitution with less power to the president, more counter powers, more power "to the people""
I'm just answering your question and staying on topic... But you try to turn this around as me being a maniac. Just like Mélenchon, you aren't really interested in an honest debate, are you?
You also reach to the disappointing "All politicians are the same to me" argument when the guy you defend is exposed as the imposture he is.
As to your deep surprise about the "revolution" part, I think you might not know about Mélenchon true ideas and background. Here's a talk he gave in 2012, in Venezuela when Chavez won his 5th term: https://www.facebook.com/StopCaSuffit/videos/extrait-dun-dis...
Here's a small part of it: "Qu'est ce qu'on fait, camarades, ça c'est un cas concret de révolution. La révolution, c'est pas un sujet de, heu... C'est un sujet concret! C'est une stratégie qu'il faut mener comme nous meme nous en avons une en France. Et après, il faut, non seulement conquérire le pouvoir mais également l'exercer de manière révolutionnaire!"
In English this would be something like "What are we doing, comrades? This is a concrete case of revolution. Revolution is not just a topic, uh... It's a concrete matter! It's a strategy that needs to be pursued, just like we have our own in France. And afterwards, not only do we need to conquer power but also exercise it in a revolutionary manner!"
That's appealing to me. You can see what I assume is Chavez supporters in the background. Chavez was en-route to his 5th term, closer and closer to achieving President-For-Live. That seems to speak a lot to Mélenchon.
Now, you say that he's not alone, and that other people in his party disagree on some subject, but that they agree on a new "more democratic" constitution. Yeah. Sure. These people define "democracy" in their own vague and populist way. "power to the people" is a overused catch phrase that's usually not precisely defined. It very quickly turns into the various parody of socialist democracies that are just dictatorships disguised as "People Democracy". You know that, right? Do I even have to explain all of that? When you here "People" too much in a politician mouth, you know he's just a conman.
You are acting like an apologist of what clearly is a dishonest megalomaniac with serious anger management issues, using the word "democracy" and "people" to justify anything without ever defining it.
Finally, it doesn't matter if I'm scared by this "FRance Insoumise", as a matter of fact he built this party around his big personality, and made it a nest of populists, opportunists and generally confused people, but nevertheless revolted, angry, chaotic and proud of it. I'm yet to hear anything honest, relevant, or interesting from them. It's just accusations, threats, whataboutism, bad faith and obstruction of debate. They are not "Insoumis", they are angry bigots, ready to be completely "soumis" to their Great Leader in exchange of some revenge against "the wealthy", capitalism, and some vague notion of a conspiracy of "the west" / US / Europe. I guess they are bored of their normal lives, they fantasize of being oppressed to justify their hunger for chaos / revolution / violence but it's really boredom from highly privileged people that think they are slaves, somehow.
It's easy being a communist in a free country. Try being free in a communist country.
Now, I'm not focusing on Mélenchon, you just happened to ask specifically about him. I'd be happy to discuss other disgusting politicians, such as, as I mentioned, Le Pen, or Zemour. There are other bad actors, of course, but these 3 are the most known and the most dangerous. Macron has done/said several thing I don't like (removing ISF taxes, his backward views on cannabis, his recent licking of Elon's ass), but he's not in the same ballpark. I persist: anyone pointing him as THE threat to democracy is completely missing the big picture.
