If I say 1+1=2, then I give a true statement.
If you question it and give an alternative result, you have questioned the truth and created something that is false, because 1 + 1 =/= 4. Unless it is 1.99999999.... + 1.99999999.... but then it isn't 1+1 and that is beyond the point.
If A is true, questioning it can lead you to any result that is or isn't A and thus not true.
Tho maybe you mean that you question things that are perceived as being true, which is not the same as being true.
The difference is between questioning 1+1=2 and questioning something like the impact of astrological influences on personality.
If someone accepts it as their truth that Astrology is correct, you can still question their perception of what is true. Question then is, do you have the right? :P
I mean, everyone has their beliefs and opinions and you don't have the right to impose yours on others. Like for example, who knows if the OP is an INFP, the OP or a stranger on the internet who had only seen a single post from the OP at the time? Yet you impose your opinion on the OP. Maybe I missed it, but where did the OP say "help me find my MBTI type" or "please comment if you think I might be another MBTI type"?
Yes, you are. Because if you question the TRUTH, you're actually trying to create a lie (as said by Qloshae). And as long as you said "question the truth" instead of "question something that perceived as being true" (which you didn't), you said that it was true. You said it was true that I'm an INFP, because you said "question THE TRUTH"...
