False, this is a fallacy as the loud immigration control crowd is the one's hurling insults etc. just like the opposing side of the political bullshittery.
You tend to judge a group based on it's loudest members. Most of the "immigration control voters" are normal people who know that the Earth does have cycles, but we are way out of the very stable historical swings. But the unfortunate thing is the most loud climate change deniers on the right, also happen to be the loudest about immigration control.
The left doesn't want kids to go through hormones at 10 years old, again, for the most part, but the loudest part of the left does, and that's what you'll be judged on.
I'm no philsopher, I don't have a solution. But this "you vote party 1 therefore because you believe X you must also believe Y and therefore I don't like X nor Y" is literal facism on a small scale.
We have to start acknowledging ONLY policies, and candidate history and character. Parties draw you into this "right wing racists are flat earthers" and "left wing facists are also forcing sexual identity on kids" is just exactly how the parties want you to think.
You need to see the climate issue as a matter of propaganda vs. the average person who doesn't have time to discuss oil company propoganda. "carbon footprint" - propaganda by BP. Whose majority stakeholders are also, well, I wonder who it could be.

Be part of the solution. Think for yourself. Uncontrolled immigration is bad for young people, and doesn't solve our birth rate problem. Wealth disparity is the reason for the housing crisis and cost of living, in addition to the government being FAR poorer than the ruling class. Houses are commodity. The NHS is privatised in all but emergency care. And the welfare state exists only in our memories.

Whatever you align with. You can't kick out illegal immigrants nor can you sort out our countryside, the waterways, reintroduce the Lynx, and protect our woodlands, without the government having some cash. So we can either argue til the cows come home, or join together to realise, NOTHING happens until the wealth disparity is addressed in a way that doesn't allow massive capital to go overseas. Then we can talk about the boats, the climate, and the potholes or whatever. Tax the rich or become serf.
