We are animals, yes.
We are intelligent beings capable of rational thought and understanding.
We are human beings that fall in the same line of nature's laws as any other animal; there are animals that practice homosexual tendencies, there are animals that are transgender, there are animals that are monogamous or polyamorous.
There are also animals that kill each other for territory, does that make it ok for us?
There are animals that kill and rape other species (Dolphins and Seals, in particular for this example), does that make it ok for us?
There are animals that slaughter the young of another male, just so their own line can propagate rather than another genetic lineage. Again, does that make it ok for us?
People need to stop using 'We are animals' as an excuse to do stupid shit. Animals are animals, they'll only ever be themselves. You can 'fuck the feelings' aspect of your post, because it doesn't make any damn sense in the context we're talking about. Holy shit.
