It is not a question of support. Merely stating what was normal and accepted as being the case in those times.
To somehow think that people should have acted according to present day mores and attitudes in bygone days is absolutely idiotic and totally pointless.
The rest of the post, another meaningless rant, is riddled with misinformation, misrepresentation and half truths. On Scottish clearances I would advise you to read a humourous, very tongue-in-cheek, piece by Robert Burns called "Address to Beelzebub" - It details what the Landowners wanted and what those cleared wished. It is a bit different to what you describe, but what would Burns know about it, he was only living and observing what was going on in real time.
