Pointing out policies that some republicans support that go against libertarian values doesn't invalidate the clear similarities of other ones.

Are you being intentionally daft?

"oops we gave up the pretense of neutrality and went full subjective"
-Politi"""fact"""

Can you refute their argument?

Why would I? I easily could, but I'm not going to, because that's irrelevant and a waste of my time.
The legitimacy of their opinion is irrelevant, the fact that its an opinion, not a fact, is what's damning.

Whether or not being tough on Russia is a good thing is subjective.

Who is tough on Russia or not can be checked with policy. That's really not all that subjective.

Of course its subjective. You need to define what is 'tough' and what isn't, how important to consider each policy, etc etc. There is no objective metric by which to measure such an opinion.
And even then you need to examine each geopolitical development through multiple lenses and their impacts versus intentions. Obama opposed Putin in Syria for years, but then flopped and helped Russia secure the country, does that count as 'being tough'?
You might as well ask what flavor tastes better or what the best piece of music is or what build is the best pvp char.

Twitter has started its mass crackdowns and is targeting conservatives using its absurd high false positive/negative methodology of "flag everyone who tweets hashtags we don't like" and/or uses cyrillic / slavic ips / .ru domains.
Their complete inability to detect automated behavior let alone link it to spooky russians who cover their tracks, coupled with their political bias and willingness to abuse their own platform and be oppressive, sure sets up the evil tech

Trump is exposing a very strong weakness by always trying to compare himself with the previous president, maybe because he's affraid he will never reach obama popularity.
