Bibili raw siya ng pepper spray kasi may exhibitionist sa loob ng jeep. Eh di lahat ng kapwa mo pasahero pati ikaw damay. Ito naman mga replies hindi man lang sabihan na bad (bordering on fatalist) idea yun.
Edit: Just to add to this: "self-defense" stuff (martial arts, taser) gives you a false sense of security and confidence. It's primary purpose is that when the only option is to fight, you have something to do/use. Hindi ibig sabihin na when some fool decides to show his dick, talks trash, or asks for your wallet, your first inclination is to do a roundhouse kick. The first, second, and third option is your safety. Kung pwede mo wag pansinin or ibigay wallet mo, that's what you do. If death is probable (hindi pa kontento sa wallet or an actual rape attempt), that's when you resort to the pepper sprays, taser, and small joint manipulation.
Ehh...looking at the thread, a lot of the top replies pointed out that it would be a bad idea. Top reply even says just to shout out that someone is showing their junk and the OP even replies to those stating it's a bad idea thanking them for letting her know. A lot of other replies are only pointing out the disgusting behavior of the exhibitionist. Granted, there are a lot of people who support it without knowing it's a bad idea, but I still feel you're misrepresenting what's happening over there.
When I first posted this, there were several replies on it (barely an hour in), most of it telling the OP to buy the pepper spray. The replies you mentioned didn't show up until after I already shared it (they're tagged blue when I went back today).
Sure, the succeeding replies eventually gave correct info, but giving bad advice on a "what should I do" thread (especially when it's the initial ones) is terrible/harmful.
Point still stands though that "self defense" on a guy passively showing his dick (that OP claims she was already able to deal with verbally) is just being vindictive and Sonny Parsons level of stupidity.
