I think I see what you are getting at, but no, I don’t find it ironic.
Above all, I think Trump is horrifying no matter how I try to look at him. He’d be horrifying to me even if all of his policies matched my own, because he’s disgusting even before I consider the politics. He’s misogynistic, abusive, narcissistic, obnoxious, offensive, greedy, deceitful, arrogant, obstinate, self-contradictory, insensitive, etc.
Next, I’d point out that “they want more government” is what some people who have reducing government as a main objective think accurately describes Democrats/socialists/leftists, etc., but that’s not the intention of the people I know who align or identify with those. They tend to care about issues, and be willing to let government address them, but the amount of size/power the government has doesn’t tend to be a major thing they are concerned with. They want government agencies to do things because they want those things done, not because they want big government for its own sake.
It’s a bit like me saying it’s ironic that Trump supporters say they want a strong America but they want to make it hard for people to immigrate who would make America stronger. Or that a wall along the south border would make us weaker because of the environmental disaster it would be, making our country poorer by damaging its non-human ecosystems.
As for Trump, going beyond his personal disgustingness, I could go on all day about what I’m horrified with about his ideas, statements, policies and appointments.
For example, his appointments to government offices. He’s consistently given them to people who were big-money donors, aren’t qualified, and are picked for an agenda that often involves undermining the organization they are appointed to run (q.v. public education, environmental protection, etc). That goes far beyond not wanting big government, adding corporate corruption and preventing agencies from doing their jobs.
Then there’s that I’m an environmentalist first and foremost. Need I go into details? There isn’t enough time in the day…
As for the size of government, I really don’t give that much of a flip about that, so it’s almost not even on my radar. So I may seem ironic to people who think size of government is a paramount issue, but I don’t. I see corruption of government as a big issue, and Trump looks like a non-stop bonanza of corrupt corporate giveaways to me, and many of those involve sabotaging regulatory agencies.
I do consider that the government is corrupt and frightening, and I don’t really want more corrupt government power in certain areas, especially the free reign given to surveil the population like it’s an enemy, security theater, corporate-agenda military adventures abroad, and the use of military-style police, or using police to quell protests. But I do want very strong environmental protections, public education, and action against abusive corporations. But all of that is about specific issues for me, and not about size of government.
