I've been guilty of this haha. Thing is, Fi an introverted and thus individual function, so that what offends one Fi valuer might not offend another. There is no way to know.
Same way there are some Ti valuers that think quantum physics explains reality and others that Elon Musk is at the heart of a deep state conspiration that aims to use rockets to turn the Moon into a death star like weapon to turn all humans into slaves(real example, a IEI told me this, and he wasn't joking). It's like if you just say what you think in a Te way, there's always a chance of a Ti valuer wanting to lecture you about their weird worldview disconnected from facts.
Maybe the best thing is just to hang out with people who have the same convictions as you, whether about Fi or Ti? If they get too offended or disagree all the time, maybe it's best to just take some distance?
You must be very afraid of hurting some Fi types in here. It makes sense that your duals are like the complete opposite "I don't care if you're offended, that's your problem"
