@Eris You dont. But you do need to understand a topic if you expect to state facts about said topic.
@Eris Thanks for proving my point, that people too stupid to pass the above test will also be too stupid to assert actual facts correctly.
@Eris I've addressed this topic in detail dozens of times on my time line. Every time the anti-vax morons just spew nonsense and ignore or arent smart enough to comprehend the reality. So yes at this point I stopped putting int he effort because its a waste of my time.
I didnt invite further discussion. Quite the opposite. The OP shows the basic level of knowledge a person needs to have before even approaching the subject, of which most anti-vaxers dont have. So it explicitly suggests people unable to pass the test DONT discuss it, the opposite of inviting it.
>I have no issue putting in the low effort
You do seem to have an issue with putting in effort thougj. Curious.
