“Men who constantly claim that ’no one wants to talk to them,’ ask yourself: When was the last time you made conversation with someone without an ulterior motive?“

"I see this all the time. Guys claim that no one wants to talk to them, but what they really mean is: 'Attractive women aren’t engaging with me.' These same men often ignore entire categories of social opportunities: talking to older people, engaging with other men platonically, striking up casual conversations with strangers just to connect." 

"If the only people you try to talk to are women you find attractive, of course you’re going to feel isolated. That’s not loneliness; that’s self-inflicted social starvation."

"Do you engage with people who don’t directly serve your personal interests? Have you made any effort to contribute to a community rather than expecting one to embrace you?" 

"The men who actually go out into the world with an open mind and a willingness to engage — rather than just seeking validation — don’t seem to be the ones complaining about loneliness."

And I think that's an important point to bring up because it can sometimes feel like that because men are facing loneliness, it's an epidemic. Meanwhile, women have been forced to pocket away emotions for years (especially in professional settings), and I've never heard that being called an epidemic. 

u/darkchocolateonly agreed, saying, "Those random stranger conversations are so great. I travel for work very often and I have them a lot in airport bars. I’ve met all types of people — economists, 9-1-1 grid tech gurus, sound operators that work on the Super Bowl...there are some cool people out there!"

In my opinion, I feel like that's the backbone of what the author of the original post was getting at, though the generalizations distracted from it. 

Not every conversation will go well and if you're a guy, you just have to accept when a woman doesn't want to engage with you — it's scary to go up to people sometimes, and it can also be scary to be approached! If someone doesn't want to talk to you, pick up on those cues, and move on. It's easier to ditch a conversation when you don't assign a goal to it (or rest your entire ego on the outcome of it).

And keep working on it. Social skills are a skill and skills need to be worked on (the whole, "If you don't use it, you lose it" applies here).
