So by your own definition he told you want to think. You didn’t care before he told you that you didn’t like it. Then you decided to like it because he told you not to like it. So by trying to go against someone telling you what you like, you allowed someone to change your opinion of it.
Which essentially defeats your own purpose and disproves the fact that you can’t be told what to think. Its just that someone needs to tell you the opposite of what they want you to think, and then you will think exactly what they want you to think.
But when somebody tries to push people along in a herd by using buzzwords, there's bound to be some opposition. Maybe that's because people who try that "bandwagon" appeal resort to it because they don't have good arguments.
I wouldn't change my mind easily about something I'd seriously reasoned out: if you've thought something through, you know why you believe as you do. But when somebody tries to tell me that everybody who counts thinks in a certain way, I'm not going to fall for it.
Maybe that's just a reaction against what they say and what they assume or maybe I've been prompted to finally thought it out for myself. When it comes to me you're probably not the best judge of which it is, anymore than I would be in your case.
But this is all getting way too "meta." When most of one's transportation is by car, one assumes that's all there is. But when you think about it, you may find that alternative means of transportation also have their uses and shouldn't be maligned or dismissed.
