'such racists?' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.

'acceptable to have time' is the wordplay.
'acceptable' becomes 'alright' (I've seen this before).
'to have' indicates putting letters inside.
'time' becomes 't' (abbreviation).
'alright' enclosing 't' is 'ALT-RIGHT'.

'for' acts as a link.
