I wouldn't consider paying extra taxes on behalf of employees political, no. Lobbying re immigration is a fair point though; I'd been considering this discussion in the context of companies pushing a political view onto their employees (per TFA) and lobbying is unrelated to that.

I'm not sure what issues you're referring to in your last para; I don't see any disputes over who's human. (I'm not in the US and am trying not to follow its politics too closely, in case it's contagious.)
