> Reddit is already a cesspool for many issues including politics, news and race/culture based questions.

So? The blast radius of those issues doesn't fully spillover into the non-political forums.

You want to know which of two different products in a particular class is better? /r/<productclass> won't be filled with political or culture-based proselytising.

Looking to buy a new laptop/car/power-tool/chair? Good advice is to be found on reddit and you may never even see a single off-topic discussion in your search.

Probably wont be long until the spammers figure out how to invade those spaces too though.

Agreed. There are certain topics which for which one cannot find anything resembling unbiased and factual, and it's getting worse as the owners continue to turn Reddit into a sanitised, ad-friendly social platform. If one is using Reddit to find relevant information, they first need knowledge about which subreddits can be trusted, and this is in constant flux.

Everywhere is a cesspool for those issues.
