What are three specific arguements that SUPPORT "Many Americans including me believe that every American deserves equal rights and oppurtunities in life. "
As long as beliefs are shared and not forced, I would agree that there can be some benefits. I would also argue for the benefits of dissent though. There have to be people who disagree, in order for a healthy democracy. If all types of people express all types of opinions, then true decision-making can result. Dissent is crucial for ensuring that every view is heard and no one gets forced to accept the status quo.
This is one of those concepts, it seems to me, which is easier to believe than to explain or justify. In order to write this essay, you'll need to think about why you "believe that every American deserves equal rights and opportunities in life. " If you can explain it for yourself, you'll be able to assume the same for other Americans, as stated in your thesis.
I assume you believe it, at least in part, because of documents, laws, and practices which demonstrate America's commitment to this concept. America was founded on that principle, as seen in the Declaration of Independence, for example. What other evidence of this sort can you find which supports your position?
You probably also believe (as do most Americans, according to your thesis) everyone deserves equal rights and opportunities for humanitarian reasons. The idea that one person would be considered superior simply by the accident of birth or geography or other rather superficial considerations. What arguments might be made to further this argument?
And you may tale this position because not doing so has created huge inequalities and injustices throughout the history of America. Think of slavery and other civil rights issues, as well as more modern implications in the areas of gays and illegal immigrants. Think about other such injustices which have occurred--and there are plenty.
A persuasive essay should, necessarily, give some credence to the opposing point of view. In this case, the idea of equal opportunities is an unrealistic goal, isn't it? Everyone is not born with the same talents, gifts, and abilities; it's virtually impossible to ensure equal opportunities when people's abilities and circumstances aren't equal.
