DS11 idolises his DF. We haven't been together for years and his DF holds very different opinions to me on a lot of things - think anti vax, anti establishment etc etc.
DS repeated one of these opinions and I'm afraid I didn't handle it very well. I tried explaining some of these opinions aren't popular and may get himself into trouble being vocal about them. DS took it badly and said I'm not allowing him his right to opinions and I'm saying he's wrong. Got into an argument and out of frustration I said his DF isn't as wonderful as he thinks he is. For years I've bbitten my tongue and not said anything like this before and I'm really disappointed in myself. DS now thinks I hate his Dad and I feel so guilty for upsetting him. All I wanted to do is help him understand about opinions and I've left him thinking that I think his dad is a bad person. I feel awful. How do others deal with situations like this?
