I don't condone violence of any kind, but these scuffles at protests hardly represent a tend in liberalism writ large.
I also searched for the relevant videos and articles to see for myself. I am not trying to explain away anything, but simply want to share my impressions.
" Lauren Southern had piss poured over her head because she questioned SJWs. " I couldn't fins two separate videos, but the one I did find showed her being sprayed with a few drops of what was later identified as red fox urine, which is used to repel rodents and other pests. Certainly unpleasant and unjustified, but it's not like someone peed in a bottle and poured it over her head.
"setting a girl's hair on fire for wearing a Trump hat. " The girl in question smugly poses in front of anti-Trump protesters for a photo. Someone behind her takes a bic lighter to her hair, probably singeing a few strands. It is actually difficult set someone's hair on fire without an accelerant. Certainly the only flame was the two second the bic was lit.
"stop touching my breasts" incident where a women kept shouting that as an excuse to assault people" . This one is much as you describe. That woman is bat-shit crazy and pushed someone off of a ledge. She should be in jail.
"feminist cuck who punched a woman reporter for asking an uncomfortable question about feminism. " After watching the video, I am appalled that a man would strike a woman, but if you listen to the moment of the strike, and where it appears to land, It seems that he was trying to knock her camera away. She claims "you just punched me in the face." but didn't cry out in pain or even flinch when the punch landed.
"Mouldylocks and her empty wine bottles" . I don't know what she was doing with her empty wine bottle. I couldn't find any videos showing her using them as a weapon or throwing them. I suspect she wasn't drinking wine from them, and was probably up to no good. The report that it was a Molotov Cocktail was debunked by snopes. And you conveniently ignored what happened to her.:
The guy punching her is a white supremacist.
EDIT: I just noticed the guy in the yellow jacket that says "Jesus will judge you" kicking someone on the ground. I am sure he is a die-hard liberal SJW
I don't think I found the SnigglyPuff video you are referring to. The one I found shows her pushing a blonde, again apparently to knock the camera out of her hand.
I also don't think I found the video, or even a story about feminists using violence to prevent people from getting into a Milo speech. The only video I found shows a college-age woman, alone in front of some doors kicking a trash can and screaming what seems to be a PMS-induced rant.

This was posted by Milo. In the video it is followed by someone challenging a woman removing Milo posters and clearly trying to bait her.
But my biggest objection is to what these protests have turned into and I think both sides are responsible for this. In the old days of the sixties and seventies, public protests were organized to bring attention to certain issues. At times civil disobedience was used purposefully and at times they turned violent. In general, they were well organized. Now, everyone wanders around with their iPhones out, hoping to capture a viral video that will support their cause on social media. Many times baiting tactics are used to provoke that violent or angry "moment." The two opposing sides mingle, setting the stage for scuffles. Both sides should be trying to convince the populace at large of their agenda. Neither is going to convince an opponent.
