1. Many companies are run by CEOs that probably don't approve of legal marijuana, and also don't do drug testing. I think this link is tenuous at best.
2. Actively rallying against same-sex marriage shows a level of commitment above just a general disproval of the idea. "I will vote against it" is a weaker position than, "I will put money into making sure that it doesn't happen."
3. Issues like the environment, and health care, while important, aren't discriminatory towards specific groups of people. Would you rather that health care and environmental-sustainability were solved issues, but discrimination wasn't?
4. Do you feel that people who only ask about (e.g.) health care issues are implicitly accepting of discrimination?
Your stance in (3) is debatable. These are both issues that have more affect on poor people. E.g. In the Northern hemisphere, the east ends of cities are generally where more poor people live because they are downwind of the pollution (if the geography allows for an east end).
That statement was less of a stance than an explanation. The parent seemed to not understand why people would be so upset about Eich's homophobia, while at the same time not question his other views. My explanation is that people are more up in arms about issues that specifically target a sub-section of people.
While health care and environment issues may affect the poor more than the rich, someone's views on either topic don't necessarily translate to "I don't like poor people and want to restrict their rights" in the same way that financially rallying against gay marriage does translates into expressing specific views about a specific group of people.
There's a big difference between a policy that has an indirect effect on a variety of groups and one that very explicitly targets a specifically defined group for formal mal-treatment under law.
And yes, systematically violating someone's 14th Amendment rights is map-treatment writ large.
