Listen, just because you have family that's wrong on this doesn't mean anything
In any case, the OP should be given the benefit of the doubt that he doesn't have these weird aversions to beautiful colors. And 145-150 is pretty dry. It's not completely vulcanized rubber yet, but it's getting there.
Also my wife's family was not into rare/mid-rare meat a while back. But I've kind of converted most of them. They still usually incinerate their own meat, but they will eat what I cook very happily. Still working on getting them to be happy with custardy scrambled eggs though.
I don't think wrong comes in here, it's
טעם וריח אין להתווכח,
30 years ago no one knew about eating meat not well done,
Not sure if it's a new trend or maybe it's just new by frum yidden,
But anyhow to say it's wrong is out of context, I love steak well done , or medium well, happens to be i just made a rib steak now in the oven on broil , both sides, then 550 bake , it had a crisp on the outside and juicy soft as butter in the inside well done , love it , I can eat medium rare but don't like it
