It would seem that some people cannot see the truth when it is right in front of them. For example "other parties do not have such a problem"

The Conservatives have 316 Mp's 37 of whom are subject to allegations of sexual impropriety. More than 1 in 10.

Labour have 259 MP's 4 of whom are subject to allegations of sexual impropriety. Less than 1 in 60.

It would seem that the Conservatives have a far bigger problem than than Labour, seemingly at least 6 times greater.
