If you lay down the boundary, and BF crosses it again...that should give you some insight into what they future may look like with him...not respecting your feelings or your requests on how not to push your buttons...

Toxic people...could be? hard to tell? for your own health set boundaries on what you are willing to allow people to say and do when around you...it may take some time reminding them...but if you give them the chances and they keep crossing...you have a good idea that contact should be limited...

Example...Dad calls and says he thinks it is nonsense...simply tell him that you know that he doesn't agree; however, you do not wish to talk about his belief on the subject. Next time dad does it...simply tell him that you already talked about this...I'm sorry I will need to end this call...Next time dad does it...simply tell him that you will not be able to take phone calls from him...

I'm a three strikes your out...you set the boundaries...if he can't respect that...then he is not a man...goes for BF too...
