What Does Loving Someone Mean?

Does loving someone or something mean that I have to hate everyone and everything else??

Why can't I like 'Akki Roti' if I like 'Aaloo Paratha'? Why can't I like 'Salman' if I like 'Shahrukh'? Why can't I like 'Physics' if I like 'Java'? Why can't I like 'Rahul' if I like 'Sachin'? Why can't I like 'Dell' if I like 'HP'? Why can't I like 'The Shawshank Redemption' if I like 'Andaz Apna Apna'? Why can't I like '100M Sprint' if I like 'Cricket'? Why can't I like 'Mc Veggie' if I like 'Pani Poori'? Why can't I like AMD if I like Intel?

Why do I have to 'choose' everytime I try to love someone or something? I feel choosing is worse than loosing. If you loose someone or something, it's not your fault. It was either your bad luck or you don't deserve etc etc. But the moment you choose, you end up with just 'nothing'.

Quite often I feel like whenever somebody tells me that he/she loves someone or something, he/she is actually showing his/her hatred towards rest of the world.

I never get this. Let me know if you get the answer. And if you do get the answer, you are truly in love.
