I'm the furthest thing from a conservative but I have spent a lot of time talking to conservatives about issues like these.

Why do you hate immigration so much even though it has proven benefits and is needed to prevent a demographic collapse.

So, at the risk of nitpicking, most conservatives don't hate immigration as much as they dislike undocumented immigration. Most conservatives are actually pretty fine with immigrants who go through the "proper" channels and who culturally assimilate but there's a widespread perception in conservative circles that undocumented immigrants bring crime and other assorted social ills with them.

There's absolutely a subset of conservatives who are just racist and don't like people who are different than they are but they're not really a large majority and conservative objections tend to focus more on things like fears about economic instability or introduction of cultural conflicts.

Why is gender a political issue? I have always just viewed it like genetics, its just what you are born with and everyone has a right to be anything they want to be.

So, point of order, it sounds like you're referring to sex. Sex is your physical genes and organs whereas gender is a more conceptual framework about your role in society, your identity, and your relationships with other people. Gender is a social construct and as such there's going to be disagreements on how that construct is...constructed.

It's more of a political issue now because issue politics predominates in neo-liberal political environments. A neo-liberal state runs best on a relatively narrow range of policy choices, most of which are six of one half dozen of the other so they don't leave a ton of room for different candidates or parties to distinguish themselves. Hence we get the introduction of wedge and social issues as a way to differentiate yourself in politics which also necessitates exaggerating the scope and scale of the issues.

Why the Euro-skeptics? The EU has proven to help and be good in almost all situations and I personally think federalization is a great idea.

A lot of conservatives see the EU as a kind of "nanny state" entity that tends to make a lot of rules about how its citizens can live. Conservatives favor a theoretical "small government" approach so tend to balk at certain ideas of regulation. The EU overrides the sovereignty of a number of member states with mandates, at least that's how conservatives see it.

There's also a subset of conservatives that see ideas of federalization and governmental concentration as a prelude to a large scale totalitarian government. You may have heard of the "New World Order" or "one world government," the EU is seen as a brick in the path leading that direction.

There's also a vein of distrust for Europeans in general in the conservative mindset, at least for American conservatives. Europeans tend to be kind of negative on a lot of aspects of America that conservatives tend to either like or at least embrace to spite the Europeans.

Trump, why do you like him?

That's a surprisingly complicated question. As many conservatives as I've talked to there really isn't a consistent, clear answer.

There's a cohort that sees him as somehow being dramatically different than other potential candidates. They tend to set aside the fact that he is, by definition, a "coastal elite" and fixate on his business credentials (such as they are...) as evidence that he's not just another politician.

I can't really say "a lot of this is wishful thinking" in a way that doesn't sound biased so I'm just not going to try. A lot of Trump support is balanced on ideas that people think Trump supports or would support and those beliefs are generally not supported by a consensus view of reality.

There's also just people who support him because he's the opposite of what Democrats and liberals want. They're the people who we tend to refer to as "being willing to set their own house on fire if it meant making a Democrat cough." Their politics is defined almost exclusively by opposition. It comes from anger, valid anger, but anger none the less.

There's also people who are more focused on areas where Trump does tend to actually do "better" in - removal of regulations, cutting spending, support for law enforcement, etc. They're not as concerned about the man as much as what he does.
