Is every shape in which two lines intersect—such as the letter T or control buttons—considered a cross that necessitates its removal, and if so, what are the consequences of deliberately leaving one or forgetting it?

This question is a continuation of the questioner's obsessive thoughts about the cross and disbelief (kufr). Not every two intersecting lines are considered a cross. And although the letter T resembles a cross, it is intended for writing. You do not become a disbeliever merely by watching channels that include the sign of the cross.
