Dude, there is playground equipment clearly seen in it almost from the get go.
What I did see was several groups of working age men sitting idle. And yes, it would be very intimidating to a mom and little kids.
OK OK, I got it, I see the playground equipment at the back, think I even saw a child running in it.
So lets be clear on your position here, because I don't want to put words in your mouth.
Are you saying that, because you and perhaps the videographer find a bunch of men sitting on the grass intimidating, it is wrong of them to do that? That they shouldn't be sitting on the grass?
They clearly are friends etc, so , is them congregating ANYWHERE a problem too?
So, what rules would you like? No men in that park? No men that are in shape, over 5 ft 10, no men dressed in casual clothes? Groups limited to 4 mean with each group a minimum 50 meters from each other?
If someone finds men sitting in the grass intimidating, that is their problem. Even more so if the true reason for the dislike is the immigration status/race of the men, which is CLEARLY the case here.
Would this bloke mind if a bunch of white bankers were sitting there taking their lunch? Methinks not.
In the same way that free speech is not dependent on whether or not other people like what I say or find it offensive, freedom TO BE IN a public park, wearing normal clothes (i.e not obscene or clothes with messages advocating violence, for instance) , not engaging in any illegal or even any activity at all other than sitting in the grass, following the rules, should not be dependent on someone else's feeling of intimidation. That is their problem.
Such a person would likely feel intimidated by similar people in almost any other location, and they have to take whatever actions within the law that they require to relieve themselves of their fear, just like a person who fears dogs would perhaps choose not to go to a section of a public park where dog owners are congregating, with their dogs on normal leashes etc.
If you disagree with my stance, then you should propose some regulations for us to hear that you feel would 'solve' this 'problem'. Be specific, state clearly what you would like to see done about this.
Cheers.
