(TLDR version at bottom)
It is my right to dislike something that is completely and vehemently opposite to logic, reason, or common sense, or is abhorrent in its own right by virtue of its disrespect to others. Someone who demonizes others religious or scientifically-held beliefs because they're adamantly convinced the world is flat or revolves around the sun or some bloody bull is, to me, a flaming !@#$%^& and a waste of space who is giving nothing to society but a headache. For example, certain members of society, including a few in my Brazilian family, who beat and berate their children for believing what they're taught in Science class in school. This is not healthy, mature, human behavior to me - this is sick, abusive, ignorant, and the anti-thesis to civilization, culture, and society. I've seen churchgoers actually throw rocks at passersby who rejected their faith. The !@#$ is this? What are we in, 200 AD?
By all means, act and believe as you wish but keep it to yourself. I hold many opinions and beliefs that other folks won't agree with but I don't go around banding into societies and proselytizing about my beliefs to others. Frankly, what I do in my private life is no one's damn business, neither is it my business what others do or believe.
Believe what you will, but keep it to yourself. If I decided to go around trying to convince everyone to worship the universe and reject their faiths I'd be just as much of an !@#$%^& as them.
For example, I come from a Christian family. I respect Christian dogma and views, but wholeheartedly reject what some Christian's uphold as a perceived monopoly on morality - something that has existed long before Christianity and exists independently of Christianity. I have no problem with Christianity, I go to church with my Christian friends when I feel like it, I know the bible better than many Christians, and I find certain aspects of Christianity to be beautiful.
BUT, the moment someone of any faith starts dogging others who don't share their beliefs, start disrespecting, demonizing, and treating people differently because of what they believe - to me they are as a lethal infection that threatens the fabric of morality and society and must be purged. Perhaps I have a pretty dystopian view of things, coming from a region replete with corruption, violent police, politicking, rampant crime, racial wars, and all sorts of chaos, but I stand by my view that if you're doing everything in your power to make innocent peoples' lives a living hell, like the Westboro folk, you're a piece of !@#$ and don't deserve the air you breathe. End of story.
TLDR;
I find it a bit difficult to have the whole "The world is wonderful, fluffy fluffy innocent perfection" mindset, despite trying my hardest to be a kind, fair, and honest person. (and being disrespected for it, to boot!) I've been to various countries, witnessed multiple cultures, and am the product of a hilarious culture/socio-economic clash of my own. What I've learned is simple: everyone is different. Everyone believes and acts differently. I believe everyone has the right to live as they wish, believe as they wish, and do as they wish - within law and reason. The SECOND someone starts demonizing the rights and beliefs of others, they become a cancerous sore on the fabric of morality and society and are only ruining the lives of innocents with their abuse.
By all means, speak your mind - but if, for example, you say you hate blacks, gays, jews, atheists, Buddhists, or demonize someone's beliefs, you'd better be prepared for all hell to break loose because if you open your mouth and pollute the airways with your bigotry then by god are you going to suffer for it.
The only people in this world I hate are stupid, ignorant people who can't seem to grasp the basic precepts of respecting your fellow man - and sadly the world is full of them. If everyone would mind their own damn business and just live their lives then everyone would be much better.
