Of course not. There are all sorts of people who are denied their pursuit of happiness all the time. Of course there are reasonable and unreasonable pursuits of happiness. The idea that people might desire unreasonable pursuits probably never occurred to Jefferson or he might have qualified the phrase.
For example, I don't like cats. I might find it extremely pleasurable to spend my evenings hunting all the felines in my general area. Should I be allowed unqualified pursuit of that happiness?
I suspect (although I doubt you would admit it) that you consider the pursuit of sexual gratification an extremely important part of your life, one which would cause you great dispair to forgo. Unless you are an adolescent such an attitude is a problem. Sex is one aspect of your personality and sexual activity is one part of your life. One of the biggest evidences that queers have a mental illness is they actually define who they are by the sex they like to have. "Normal" people don't do this. In fact, the only time anyone would ever declare themselves to be heterosexual is in response to a challenge that they might be queer.
Shalom.
That depends on whether the cats in question are feral cats, or domestic cats and thus, someone else's property.
I am not an adolescent, however, I don't have to accept your definition of my concerns over the issue as being purely driven by my "needs" for sexual gratification, nor do I have to accept your generalized standard.
BTW, heterosexuals define who they are by their sexual activities as well.
May I also add that by using words such as queer, etc. you are giving weight to their argument.
I know of no such nationality as "queer", I was under the impression that we were discussong the individual rights of American citizens.
