I would say these are slightly irritating. Not mildly infuriating in the way that people who use nonsense terms like "eco-fascist" are.

Anyone sane understands that "be gay do crime" is not inciting criminality but obviously statement of opposition to unjust cultural norms.

Similarly "killing people makes nature alive" obviously seeks to highlight the current incompatibility of human goals with the needs of all life on the planet (including humans).
