Police should investigate non-crime hate incidents only when these risk "imminently breaking the law", the Conservatives have said.
Shadow home secretary Chris Philp, the policing minister in the previous government, said the police guidance on dealing with hate speech should be updated to ensure officers were not "policing thought" or "free speech".
His comments follow a row between Telegraph columnist Allison Pearson and Essex Police, who are investigating an allegation she breached the Public Order Act in a social media post last year.
A non-crime hate incident is recorded where no criminal offence has been committed, but the person reporting it believes it was motivated by hostility.
