When selecting argumentative essay ideas, there are several issues that one has to take into consideration. The first thing and also one of the most important things is that the selected ideas should be able to sustain an argument. An idea that can sustain an argument is one that has people having strong beliefs in either side of the arguments.
A good example of such an idea is “was the war in Iraq justified” If you were to ask such a question to a staunch republican in the US then the answer that you will receive is a strong yes and the reason for this is that no one gets to strike the US and get away with it. Even if one were to argue that the weapons of mass destruction theory that was used to convince Americans to support the war turned out to be non-existent, a staunch republican will still stick to his argument that terrorists struck the soil of the US and someone, preferably the countries seen as offering support to such terrorists had to be hit back as a warning to other nations never to support anyone who is aggressive against the US.
If you were to ask that same question to a staunch democrat, the n the answer that you will receive is a straight no. The argument behind the no answer being that despite terrorists hitting the US, there was no proof that Iraq had anything to do with then terrorists and besides, the weapons of mass destruction that were said to be manufactured in Iraq turned out to be non-existent.
The other point to note when selecting ideas for argumentative essays is that one should avoid ideas that are too sensitive as these could cause more trouble than it is intended. Basing arguments based on religious beliefs should be a no go zone given the level of emotions that some individuals regard anything to do with their religious beliefs. It is always dangerous to base ideas on religious beliefs without being in danger of evoking strong emotions.
Also, when selecting ideas for an argumentative essay, one should try and be creative. Do not select a topic that has been the subject of many arguments because chances are that you will not be able to state anything new in the argument or state something that people already have not heard of in arguments. Teachers and lecturers like creativity and controversy.
To avoid selecting issues that have been previously been argued about and reargued, one could try and select an argument based on recent occurrences. Even so, one should ensure that the line of argument that one selects is one that is full of many ideas and be one that can be strongly be argued from both sides.
