Screw what others think of LBT. You like it? Then watch it and don't care what they think. They're the ones missing out on something great.
I won't pretend not to be an LBT fan in public. If anyone asks me I won't deny it and I have been drawing LBT characters in places where others can see me doing it. However, I won't go around forcing my LBT enthusiasm down anyone's throat by wearing LBT T-shirts, marks reading "I love the land before time", or items which I may display in my personal collection but not brandish in public.
Members of this very community here have expressed dislike for some products, or characters, or even fans of particular products or characters. Members of this very community here have expressed their dislike of movies which they regard as "childish". For example, I could name members of this community (I won't give names though) who would definitely wrinkle their noses and hold prejudices against someone wearing a Barney T-Shirt (does purple dinosaur sound familiar to anyone?). By what right could we demand more tolerance about our enthusiasm for LBT than we are willing to give to enthusiasts of other franchises?
I am also a holder of prejudices.
If I saw some grownup with a Barney T-Shirt in public I would consider him no less strange than others would consider me as strange if I was wearing a Chomper T-Shirt.
My point is that I would not hide my LBT enthusiasm, but neither enforce it on anyone by walking around in or with LBT merchandise all the time. I could not blame anyone for considering me a weirdo (in a negative sense of the term) if I did. It is a good thing to go your own way and be an individualist, but it is a bad thing not to pay any attention at all to what other people will think of you.
