> The ones in 1989 were violent all over Eastern Europe

That's the point. Because the 1989 were violent, allowed for 2017 to be effective. Peaceful protests are easy, but peaceful and effective is hard.

> Anti Trump protesters that destroyed private property are just vandals who can't accept the outcome of a democratic election.

I can agree with that. They\ ones that came to DC burned a few trashcans, broken windows and set a car on fire. What they perhaps didn't realize is that DC has pretty steep penalties for that kind of stuff, and now many of them have felonies on their record (in US those are the more serious charges that stay with you for a life and often prevent people from getting a good job in the future).

Also Chomsky has pointed out that Antifa is a great gift to the right.

That's an interesting way to think about it, but perhaps correct as I think in aggregate their action alienate more people than it inspires and in general fail to make the government afraid so their demands are just not heard and paid attention to.

> The ones in 1989 were violent all over Eastern Europe with the exception of Czech Republic.

This is BLATANTLY false, please get your facts straight! https://en.wikipedia.org/wiki/Revolutions_of_1989

The Wikipedia article is pretty light on details and in some cases even inaccurate. Even though only in Romania the regime change was violent, it doesn't mean that in other countries protesters were not initially arrested and/or beaten by the police/regime forces. I know this from first hand experience because I've lived in those times. In the GDR protesters were arrested and beaten. Even in Czechoslovakia a protest was crushed by the police. In Poland is was mostly nonviolent because they started to weaken the regime since 1980 mainly through strikes and worker's protests. The breakup of Yugoslavia led to the Balkan wars. In Romania people were shot dead in the street, something the wikipedia article fails to mention. You can read a more accurate description of the Romanian 1989 revolution here:

The NSF (PDSR/PSDR after that, currently PSD) mentioned in the introduction is the continuator of the Romanian Communist Party. They're the ones who siezed power and split into or infiltrated most if not all mainstream political parties. They're also the ones currenly in power. The current protests are also against them.
