I would consider making people to vote for a criminal dictator to be more harmful than selling drugs, the former is destroying way more lives than the latter. And I am someone who would vote for more enforcement and regulation of bans on drugs.

No matter your political opinions, the ability to target political advertisements hardly seems like the nightmare you all act like it was.

Multiple people keep talking about selling hard drugs in the comments. Seems a tad dramatic.

Showing ads (not necessarily political ads) can be harmful. Very easy example is of course ads for gambling sites.
