This simply isn’t true. The minority party, GOP or Dem have been known to support speakers of the opposite party when it suited their purposes.
Look at any of the elections since 2001 (and probably well before). Not a single vote (at least that I saw) for the opposition from either party - https://en.m.wikipedia.org/wiki/List_of_Speaker_of_the_United_States_House_of_Representatives_elections
This is why you’re getting down voted, it’s not about what politics it’s that you aren’t giving correct information.
Nah, the downvotes are weird partisanship. The rest of the world knows that these parties sometimes cut deals on speakers.

On Tuesday, Democrats voted unanimously alongside Republican Rep. Matt Gaetz of Florida and seven other GOP members to remove McCarthy as Speaker. Despite talk over the weekend that some Democrats might cut a deal with McCarthy to save him, the Speaker ultimately refused to offer members of the opposition party any concessions, leaving Democrats united against him. In the narrowly divided House, only a handful of Republicans needed to join Democrats to create the majority needed to win the vote.
