To sum up my position, I feel abortion should definitely be allowed. I find it funny when religious people try to say it is killing another person, when in reality it is not anything of the sort. Your religion does not mean you can be ignorant to all science. At the period when abortion is allowed, it is not a self-supportable alive human being. It has no sense of awareness and is basically "dead."
The argument of how life as small as bacteria on other planets would be classified as life, while a human to be is not, is pathetic and flawed. The bacteria is obviously self-supporting and is alive with no aid, while the fetus is technically, not due to awareness. It is not technically "alive" while a bacteria on Mars is much more self-supporting and is alive.
