We kept all our sons intact, but never really discussed it with my husband's parents. He is one of five boys, all circumcised. Brothers 3 and 4 know about circumcision from me and are against it.
Yesterday I posted a video of a circumcision on my FB profile, with an apology to those who didn't know what really happened. My MIL saw it and freaked out. She never knew what really happened and was horrified. Today she sent an email apologizing to all her sons and asking them to not do it to any children they have (so far we have the only grandkids.) She even is going with us to Washington DC for the protest in March! I feel terrible at the pain she is feeling now, but I hope that with her support, the other sons will not do it to their future kids.
