If you can’t rule out the possibility of non-response bias caused by unobserved characteristics then your interpretation of the results should be within the confines of “those who are likely to respond to my survey” and not their reported demographics.

i only hope you apply this level of evenhanded critique to all studies ever done with voluntary respondents (but also whenever i do bigger surveys i try to be careful to remove incentives for nonresponse that might be related to the thing im trying to test)
