The first page of results for "id laws voter suppression" turned up similar statements from the WaPo, Atlantic, Wired, Vox, and quotes numerous politicians. Your "no one thinks that" is not in line with reality.
That said, the Republican path of establishing voter ID laws is often part of a pattern of "let's make it hard for the poor and working class to get proper ID, and to vote".
Reducing early voting, not making ID cards free, etc. Voting should be a universal right in this country. The government should be putting in maximum effort to assist everyone who wants to vote, to be ready when the time comes, and enable early voting as much as possible.
Just about everyone I know who leans even slightly left here in the US believes that requiring ID to vote is defacto voter suppression.
Also it seems like states are making it easier to get an ID [0]
