The sympathy for Laika is understandable and very human. It is just.

However the instrumentation of her death is anti communist. Why did the Western world so much care for one dog when they did kill countless animals - including dogs - for commercial usage (and I don't even mean animal agriculture!) with little and no scientific gain?

Anticommunism. The Canine Defense League (a name that was chosen for its continuity) was leveraging Laika progpagandistically and did quite a bit of Sinophobia during that time, too.

KINGDOM OF CONSCIENCE – Moralists don't really have beliefs. Sometimes they stumble on one, like on a child's toy left on the carpet. The toy must be put away immediately. And the child reprimanded. Centrism isn't change -- not even incremental change. It is control. Over yourself and the world. Exercise it. Look up at the sky, at the dark shapes of Coalition airships hanging there. Ask yourself: is there something sinister in moralism? And then answer: no. God is in his heaven. Everything is normal on Earth.
