I'm against bachelor parties for several reasons. First of all, going to a stag party gets you wasted and stupid, in other words, you will be so drunk that you won't be able to control yourself.
Also, these kind of parties usually happen before getting married, and this is the worst idea. If someone is going to get married he needs to learn how to control himself and how to avoid going to Vegas with friends instead of acting as a child.
A part from that , you never know what might happpens when you get drunk, for example, the movie hangover, they were traumatised by the next morning. Moreover, I disagree with the idea if have bachelor parties whether for men or women. If the men can't control themselves what the women will do !. So i think they will face more consequences than men
