Seriously language wars are silly. I've used lots of languages in my career. Every language has its joys and quirks. Arguing about languages is a silly waste of time. I compare it to amateur vs. professional photographers: amateurs talk about cameras and equipment. Professionals study light and composition and take photographs. Amateur programmers talk about tools and languages. Professionals write good code in whatever language is required or best for the job. You won't be able to pick the language most of the time if you plan to work for money, so get used to learning new languages and appreciating them for what they are.
Of course you can love all languages, just as you can love all foods, love all cities, love all... well, you get the picture.
Admittedly, some languages are harder to love than others, but all the ones with more than fifty users are doing something right, even if it's just "running the critical software we wrote fifty years ago and don't have time to port"
And, as with sports teams, sometimes circumstances dictate that you declare your fanaticism for the local team and discreetly remain silent about any other teams.
Thus, knowing more languages, and actually enjoying most of them, with little to no bias, is a good trait to have, in my opinion.
