It's not nonsense. Russia is waging a propaganda war in the west. Results are clearly visible in the last 5 years or so.
Even in my country that was occupied by USSR at one time, there are now very vocal pro-russian agenda voices, especially on social media, news comment sections and or alt-news websites. It's ridiculous.
And what's this website anyway? Someone created an anonymous website to spread some onesided info about a feud with some wikipedia editor he doesn't like.
Out of curiosity, I looked up Galloway. He isn't really serious about what he writes about UK/US/Syria. Just filter his twitter for syria keyword. It's all just some one-sided polemic, often based on leading questions. It's not even reporting. He comes of as some kind of misinformed activist with non-obvious agenda.
Anti-war? That surely must be a joke. He has 151k tweets and barely mentions destruction of Raqqa by US air campaign that was going on for 5 months. He mentions Kobani, another city US bombed and shelled to the ground, precisely once - to send people to RT/Sputnik for info about that. All these things and others were significantly more influential actions by the US war machine in the region, and incomparably more deadly and injurious to innocents. He's not even anti-US/UK war machine, consistently.
Yet US does some token attack on Assad's infrastructure, and he spreads alarmist nonsense for days, even insinuating that he might be killed by UK government. I don't get him. Perhaps he's just trying to look certain way to UK citizens, and it's all just posturing/signalling.
He didn't even mention any of the Assads war crimes, or what he did to fuel instability and war in the region. No mention out of 151k tweets. That's anti war?
