This claim is not completely false, the title of the headline is just misleading to create a false claim. This title misinforms the public about the bill being put up to the Hawaiian senate that is "Awaiting Senate action after passing the House, HB2079 grants a de-facto immunity and asylum in Hawaii for any kidnapper who claims to be helping a child receive so-called ‘gender-affirming’ treatments," as of from Saturday, March 16, 2024. Hawaii is not necessarily making kidnapping "legal", it is just giving less harsh punishments for kidnappers when found guilty.
Here is the link to the bill posted by the Hawaii Free Press in the state of Hawaii:
