Subjective truth doesn't exist

If you tell me I'm wrong while telling me there is a subjective truth, then you've already defeated your own belief system 🤣. If truth is subjective, then anything anyone says must be validated and stated to be true. Full stop. If not, then you do believe there is a singular truth, or at a minimum you just believe I'm just to stupid to form any number of possible truths? Either way, your belief system gets defeated immediately when you tell me I'm wrong 🤷‍♂️.To be clear, I don't think I'm always right nor do I believe I never see an event incorrectly. I also know that we can both be wrong. That way we can learn to discuss the facts while then addressing the feelings and opinions to solve the problem and avoid a recurring event because we never solved the truth first.
