Many consider wife carrying a sexist activity. Humans have evolved considerably since the days of cave men carrying women off to their caves. Therefore, women should be treated with more respect; not like something that a man owns and can carry around like a possession. In short, wife carrying is a sexist activity because it presents women as being weaker than their husbands.
The act or sport of wife carrying is definitely a sexist activity, as it treats women like objects - specifically weights. I don't believe this is a good idea to further progress women's rights, and this sport should definitely be reconsidered. There are other objects that can be carried that would still be interesting to an audience.
Wife carrying is a lighthearted competition that doesn't cause anyone any harm. It's not sexist to say that the average male is stronger physically than the average female, it's just a fact. The women and men involved in the game do so willingly. There's no reason for others to spoil their fun by coming up with manufactured outrage.
No, I do not think that "wife carrying" is a sexist activity because it is an undeniable fact that most men are physically stronger than women. The event is for laughs and I do not think that it is anyway sexist or demeaning for women to partake in this event with their spouses.
