I assumed you said that (about how men are far more likely to be abusers) to try to mitigate any reactions that take your very reasonable comment out of context. Any time someone points out that abuse or injustice can happen from the non-typical side of a binary situation, someone inevitably jumps in with a “well achually…” response. Sometimes it’s said with the best of intentions. Sometimes it’s just trolling our pushing a personal bias.
I disagree with others who say you are perpetuating something negative by saying that. That’s clearly not what you are doing. You are just trying to provide a preemptive response to an inevitable counterpoint. Your overall point was well-made and reinforces the tragic but insightful story behind this post.
I hope you and your dad have found peace and happiness away from your abusive mom.
