I don't like that you are trying to mislead others.

The deception you've described is of course minor and maybe you don't lie about important things. But it seems a dangerous strategy, for your own epistemic hygiene, to be casual with the truth. Even if I didn't regard it as ethically questionable, I wouldn't be habitually dishonest for the sake of my own mind.
