Your country is built on representative democracy, and that representative democracy has decided that abortion is a legal practice. You're perfectly entitled to vote against it, to contact your representative in the government and have your say - but advocating violence or any kind of force against private persons or property, whose actions are protected by that law, simply because you do not agree with it, constitutes an attack on your entire country's founding principles and democracy itself - and to this I could say, with rather more validity than your own ilk who commonly abuse the phrase, "why do you hate America?"
Oh, and thanks for giving a link to a site with gruesome medical pictures - nothing helps a rational debate quite like forcing instinctive, visceral revulsion on people and bypassing conscious thought altogether. The problem with that is, I'd have exactly the same reaction to pictures of, say, an appendectomy - all surgery is gruesome. That you would link to such a known irrational, extremist, terrorist organisation at all and expect us to take anything you say seriously is simply insulting.
I also notice the linked site provides no source or accurate description of said pictures - without that, one cannot possibly take them to be representative of anything specific. They could be of the results of an abortion carried out within the legal timeframe, or they could be of a natural miscarriage, a stillbirth, or some other birth complication, or they could even be entirely fake. It also seems that supposed abortion images in such collections (invariably without any accurate descriptions or verifiable source) are always wildly inconsistent with each other - medical procedures are pretty standardised, so the lack of coherency doesn't just make specific conclusions impossible, but casts serious doubt on the validity of the collection and, indeed, the sincerity of its collator. And, as has been pointed out, legal abortions usually occur on a tiny clump of cells that's barely recognisable as mammalian, let alone human, yet these are always inexplicably absent from the shock-photo collections of anti-abortionists.
