Let’s not be so harsh. I don’t think anybody was saying or thinking that. There is a difference of roles between men and women, and the question was whether this practice is respectful of that difference. I think the answer clearly is “yes,” and there is nothing wrong with women being altar servers, but for prudent reasons, it might be preferred that men take on that role if possible, because perhaps it might give an inaccurate impression of what the job entails.
Once, when I attended a prayer group at church dominated by women, I constantly felt out of place and unable to relate because the discussions tended far too much towards feelings and the like and before long, I was too uncomfortable and no longer able to make myself attend. It might be that women wouldn’t feel out of place in a men’s group, but with men, it’s different, and it’s not a question of ego or needing to feel “macho” but simply an innate difference in how we see the world and the fact that our minds work a little differently. Men need to be respected just as much as women need to be respected.
That doesn’t make me a sexist or make me think that men are better than women, but is simply a reflection of the differences between men and women and similar to why men might prefer action movies to chick flicks or why boys prefer to play with trucks and girls with dolls.
