It should be of no surprise that a conservative, religious group is following the teachings in a holy book which states that premarital sex, adultery, homosexuality, beastiality, and incest are sexual sins and strictly forbidden.
Now, you may not agree with any of that, but many are homeschooling because they believe that the secular, anything goes, puplic school/society culture is ungodly and sexually sinful. Again, you may think that those beliefs are a bunch of bunk, but they have the right to have a co-op with whomever they want. To them, it's a serious matter.
Also, the church historically practiced what could been seen as shunning. That if a person was continuing in a sexual sin and refusing to repent, that person was to be excluded from the group until they repented. The example in scripture was of a man in a sexual relationship with his father's wife. The church members were chastized for allowing the couple to be in their midst and part of the community. The community was instructed to exclude the couple until they repented and stopped their sexual relationship. The co-op you're talking about is probably grappling with this issue in the situation you (OP) mentioned.
Again, you may totally not believe in any of it, but those homeschool families, like others from other conservative faiths, have a right to follow their religion, and have freedom to assemble with those who are like-minded.
ETA I am talking about this issue in general. I know that there are young people in the church who struggle with fitting in and being accepted. Church members are all grappling with this issue.
