This video is everything I hate; bullying a physically weaker person (an older lady in this case), his misguided views on masks and the notion that what he thinks is somehow worthy of vocalising to everyone around him. The problem is that he likely does not even know what he things- nobody can seriously 'aggressively' make a point about masks and actually understand why they don't like them.
What on earth are the other passengers doing just sitting there and allowing that? Maybe it's a freedom of speech thing, but he simply does not deserve that privilege.
