I don't really think the whole "trees feeling pain" thing is meant to be taken literally (although I've personally known some radical leftists who have legitimately held such opinions) as much as it is meant to be a general example of the hypocrisy and nauseating irony of the liberal/progressive point of view.

These liberals of who I speak are the same ones who fight tooth and nail for chickens rights, who go apoplectic over the conditions that animals face in slaughterhouses, etc. Granted, the animals we eat for food often do endure horrible conditions that should be dealt with in some way to become more humane. The point of it though is that while these people scream bloody murder and are appalled beyond belief at the mistreatment of animals, they have no, or very few, qualms with the destruction of a defenseless unborn human being. In fact, they often ENCOURAGE this destruction.

Hidden camera videos portraying the deplorable conditions that animals face in the meat and poultry industry are greeted by widespread and total disgust, a huge, collective rageboner for the leftists. Yet hidden camera videos surface that reveal the grotesque and amoral black market for dead baby parts, being supported by taxpayer dollars no less, and the left tries everything in their power to discredit these videos and write them off as nothing more than partisan propaganda. It's sickening, it really is.
