Ice cream preference is a matter of taste, Christianity is a matter of fact. But even if Christianity were bunk, the idea that anyone should believe that truth is truth just because they think it's truth is ludicrous.

Matters of faith are matters of taste, that's what makes them matters of faith. It is not a coincidence that children tend to prefer the same kind of food and religion that their parents enjoyed. They both are matters of taste that tend to be drilled into you at an early age.

Moreover, if there were evidence, differential equations, and other mathematical proofs which would establish, for example, that Jesus Christ is the son of God, the belief in such would not be a matter of faith.

...the idea that anyone should believe that truth is truth just because they think it's truth is ludicrous.

Is something red because you think it's red or is it red in-itself? If it's red because you think "red," doesn't thinking the thing red make it red? On the other hand, if an object is red in-itself, where in the object is its "redness"? I think we often speak of things being true because we think them to be true.
