What you will find if you actually try to become an activist on these issues is that "getting your platform noticed" is very much non-trivial. There is a wide and deep gulf between "having a position on an issue" and "having a mainstream newspaper write that you have a position on an issue". A particular advocacy group may be spending a ton of effort and money to get noticed about an issue, and still have a complete press blackout on the issue, and it is not necessarily their fault. In the end newspapers write about what their owners want them to write about, not what would be best for society.
